Jawaban:
a)
Carilah luas bangun A
A dapat dipotong menjadi segitiga dan persegi panjang:
Luas p. panjang:
3 x 5 = 15 cm²
Luas segitiga:
½ x 3 x (11 - 5) = 9 cm²
Luas total A:
15 + 9 = 24 cm²
b)
Luas bangun A = Luas bangun B
Rumus luas jajar genjang:
alas x tinggi
Luas bangun B = 24 cm²
6 x h = 24 cm²
h = 4 cm
(a) The area of shape A
Area of rectangle = 5 x 3 = 15 cm²
Area of triangle = ½ x 3 x (11 - 5)
Area of triangle = ½ x 3 x 6
Area of triangle = 9 cm²
Area of shape A = 15 + 9 = 24 cm²
(b) Area of shape A = Area of parallelogram B
24 = 6 x h
h = 24 : 6
