The figure is not drawn to scale. Find the area of the shaded triangle.
1. The figure is not drawn to scale. Find the area of the shaded triangle.
Jawaban:
484
Penjelasan dengan langkah-langkah:
Area of triangle = Base x Height
= 22 x 22
= 484
So, the area of the shaded triangle is 484
2. The figure is not drawn to scale. What is the shaded area?
Penjelasan dengan langkah-langkah:
triangle 1
= 1/2 x a x t
= 1/2 x 10 x 12
= 60 cm2
triangle 2
= 1/2 x a x t
= 1/2 x 8 x 10
= 40 cm2
triangle 1 - triangle 2
= 60 cm2 - 40 cm2
= 20 cm2
3. In the figure below not drawn to scale, ∠ABC is 65°. ∠BCA is 59°. Find ∠CAB. butuh hari ini plis
Answer:
∠CAB = 56°
Explanation with steps:
∠ABC = 65°
∠BCA = 59°
the sum of the angles in a triangle is always 180°, so
total angle of triangle = ∠CAB + ∠ABC + ∠BCA
180° = ∠CAB + 65° + 59°
∠CAB = 180° - 65° - 59°
∠CAB = 56°

8. In the figure below not drawn to scale, ABCD is a square and CEFG is a rhombus. ∠GFC = 36°.Find ∠FGD. Please answer?
Jawab:
∠FGD = 72
Penjelasan dengan langkah-langkah:
- jml ∠ segitiga = 90
- segitiga CGFC merupakan segitiga sama kaki.
- ∠GFC = ∠GCF = 36
- jml ∠ segitiga = 180
- ∠GFC + ∠GCF + ∠CGF = 180
36 + 36 + ∠CGF = 180
72 + ∠CGF = 180
∠CGF = 180 - 72
∠CGF = 108
jadi...
∠FGD = 180 - ∠CGF
∠FGD = 180 - 108
∠FGD = 72

12. the scale of the figure below is 1 : 200.the actual area of the figure is....maaf kalau gak ada gambar kotak aku kasih tau panjang dan lebarnya : 7 cm dan 5 cm
7 cm : [tex]\frac{1}{200}[/tex] = 7 x 200 cm = 14 dm
5 cm : [tex]\frac{1}{200}[/tex] = 7 x 200 cm = 10 dm
area : 14 dm x 10 dm = 140 dm2
13. a square pool is going to be drawn in a map to a scale of 1:150.(i) Find the real area of the pool if the side of the pool in the map is 2cm(ii) Find the map area of the pool if the read side of the pool is 30m
1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1=16
Jawab:
1.9 m²
2.20 cm
Penjelasan dengan langkah-langkah:
1.real area = pxl
=2(150) x2(150)
=300 x 300
=90.000 cm
=9 m²
ii.map area :
real side =30 m
=3000 cm
map side = 3000 x 1/150
=3000/150
=20 cm

18. Find the area of the figure
Jawaban:
dik.
persegi panjang
panjang p = 10 m
lebar l = 6 m
segitiga
alas a = lebar persegi panjang = 6 m
tingg t = 7 cm
luas persegi panjang
= p x l
= 6 m x 10 m
= 60 m²
luas segitiga
= /2 x alas x tinggi
= 1/2 x 6 x 7
= 21 cm²
luas gabungan = 60 m² + 21 m² = 81 m²
19. the following figures arnt drawn to scale find f
Segitiga = 180°
Segitiga atas ketiga sisinya sama
Segitiga atas = 180 ÷ 3 = 60
Segitiga bawah = 180-93 = 87°
Sudut f = siku siku dengan sudut diatasnya
Sudut f = 60 + f = 90°
= 90-60 = 30°
Sudut yang satunya = 180 - (93+30)
= 180 - 123 = 57°
20. 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.
