1. A figure is made up of a rectangle and a semicircle as shown in the diagram below. what is the area of the figure?
Jawab:
Area itu bahasa inggris dari Luas, maka
Area of square = S x S
= 7 x 7
= 49 cm²
Radius = Diameter / 2
= 7 / 2
= 3.5 cm
Area of [tex]\frac{1}{2}[/tex] circle = [tex]\frac{1}{2}[/tex] x [tex]\pi[/tex] x r²
= [tex]\frac{1}{2}[/tex] x [tex]\frac{22}{7}[/tex] x 3.5²
= 19.25 cm²
Are of the figure = 49 + 19.25 = 68.25 cm²
Penjelasan:
phi [tex](\pi )[/tex] untuk [tex]\frac{22}{7}[/tex] digunakan apabila jari-jari/radius berkelipatan 7, sedangkan
phi untuk 3.14 digunakan apabila jari-jari/radius tidak berkelipatan 7

3. A glass house is in the shape as shown in the figure . calculate total area of glass needed and calculate the volume of the glass house
Jawab:
Total Luas seluruh bangunan = L prisma segitiga + L balok
= 248 m² + 292 m² = 540 m²
Total Volume seluruh bangunan = V prisma segitiga + V balok
= 60 m³ + 336 m³ = 396 m³
Penjelasan dengan langkah-langkah:
Bangunan ini adalah gabungan dari prisma segitiga dan balok.
Diketahui :
Prisma segitiga : alas = 5 m
tinggi alas = 6 m
tinggi prisma = 11 m - 7 m = 4 m
Ditanya : L = ?
V = ?
L = 2 X Luas alas + Keliling alas + tinggi
= 2 X (1/2 X 5X6) + (5+5+6) x 4
= 2 x (15 + 16 x 4)
= 2 x 124 = 248 m²
Volume = Luas alas X tinggi
= (1/2 X 5X6) X 4
= 60 m³
Sekarang kita hitung balok.
Diketahui : p = 8 m
l = 6 m
t = 7 m
Ditanya : L = ?
V = ?
L balok = 2 (pl + pt + lt)
= 2 (8X6 + 8X7 + 6X7)
= 2 (48+56+42)
= 2 x 146 = 292 m²
Volume balok = pxlxt
= 8 X 6 X 7
= 336 m³
Total Luas seluruh bangunan = L prisma segitiga + L balok
= 248 m² + 292 m² = 540 m²
Total Volume seluruh bangunan = V prisma segitiga + V balok
= 60 m³ + 336 m³ = 396 m³

5. What is the missing value in the equivalent ratio of 42 : ______ = 7 : 10
Jawaban:
60
Penjelasan:
42:... = 7:10
42:7=6
The different of ratio is 6.
7:10 = 7(×6):10(×6) = 42:60

8. The figure is made up of a square and trapezium. The perimeter of the figure is 60 cm. Find the area of the figure. Use the steps.
Jawab:
The area of the figure is 188 cm².
Penjelasan dengan langkah-langkah:
Form that figure, we know that A and C are both squares. Therefore, the length of the rightmost side of the figure is 8 cm.
Let s be the length of C’s sides.
Given that the perimeter of the figure is 60 cm, we can get:
(14 + 2×8 + 3s) cm = 60 cm
⇔ 14 + 16 + 3s = 60
⇔ 30 + 3s = 60
⇔ 3s = 60 – 30
⇔ 3s = 30
⇔ s = 30/3
⇔ s = 10 cm
Let A be the area of the figure, we can find:
A = the sum of all areas
⇔ A = area of square A + area of trapezium
⇔ A = s² + ½(base+top)×height
⇔ A = 10² + ½(14+8)×8
⇔ A = 100 + 11×8
⇔ A = 100 + 88
⇔ A = 188 cm²
CONCLUSION∴ The area of the figure is 188 cm².

10. I try to figure in the answer of what the function of the organization is Soal eror?? A. I B. Figure in C. What D. Is
Jawaban:
The error:
B. Figure in
Pembetulan:
Bahasa Inggris dari mencari tahu adalah figure out, bukan figure in (Phrasal Verb).
Penjelasan:
I try to figure in the answer of what the function of the organization is.
Pembetulan:
I try to figure out the answer of what the function of the organization is.
Phrasal Verb yang tepat untuk kalimat di atas adalah figure out bukan figure in. Karena yang bermakna mencari tahu adalah figure out, bukan figure ini. Kalimat di atas juga bukanlah kalimat tanya, meskipun terdapat kata tanya "what" dan "is". Maka dari itu, peletakan kata "is" di akhir kalimat, sebagai tanda yang menunjukkan bahwa kalimat tersebut adalah kalimat positif atau berbentuk pernyataan, bukan pertanyaan.

12. figure B is made up of four identical right angled triangles as shown in figure A. Four times the perimeter of figure A is 96cm. The perimeter of Figure B is 48cm. What is the lenght of XY?tolong dibantu sesegera mungkin ya.. thanks. #math#matematika#triangle#perimeter
Jawaban:
6 cm
Penjelasan dengan langkah-langkah:
4(Keliling gambar A) = 96 cm
Keliling gambar A = 24 cm
Gunakan tripel Pythagoras
Segitiga 3-4-5 adalah segitiga siku-siku dan kelilingnya adalah (3+4+5) cm = 12 cm
Kalau mau dapatkan segitiga siku-siku dengan kelilingnya adalah 24 cm, maka tripel Pythagorasnya adalah 6-8-10 (Cuma dikali 2). Karena XY(alas segitiga) lebih pendek daripada tinggi segitiga, maka XY = 6 cm
13. The perimeter of the figure is . . . .
Penjelasan dengan langkah-langkah:
Perimeter = keliling
Keliling = 10 + 3 + 5 + 1 + 3 + 1 + 2 + 3 =28m
14. a piece of wire 144cm long is bent to form a semicircle as shown in the figure. find the diameter of the semicircle, giving your answer in metres.
Jawaban:
0,46 mPenjelasan dengan langkah-langkah:
A mean a piece of wire = a circumference of a semicircle
[tex]c = \pi \: d \\ 144 = 3.14 \: d \\ d = \frac{144}{3.14} \\ d = 45.86 \\ d = 46 \: cm \div 100 \\ d = 0.46 \: m[/tex]

15. in the figure ABCDE is made up of triangle ABE and square BCDE. AE=ED=8cm. find the area of the figure
Jawaban:
From the questions we know that BCDE is a square and ED = 8cm,
which means BC=CD=ED=EB= 8cm
That means the area for BCDE is side x side or 8 x 8 = 64cm²
since AE = ED and we know that triangle is half of a square
that means the area for ABE = 1/2 x 64= 32cm²
ABCDE = BCDE + ABE
= 64cm² + 32cm²
=96cm²
