Question

. In the figure, AB = 20 m, BC = 21 m, AD = 10 m and
DE = 10.5 m. Find the area of the shaded region.
C
21 m
D
10 m
10.5 m
A
B
E
+ 20 m​

Answer 1

Answer:

Area Of Triangle Abc = 1/2 (AB)(BC) = 1/2 × 20 × 21

= 21×10 = 210m²

area of triangle ade = 1/2 (AD)(DE) =1/2 × 10 × 10.5 = 5×10.5 = 52.5m²

=> area of shaded part

= area of triangle ABC - area of triangle ADE

= 210 - 52.5 = 157.5m²
