Question

4. Find the area of shaded and unshaded portions.
22 m,3 m,18m,3m​

Answer 1

Answer:

Length = 22 m

Breadth = 3 m

Area = lb = 22 × 3 = 66sq.m

Length = 18 m

Breadth = 3 m

Area = lb = 18 × 3 = 54sq.m

Side = 3 m

Area = S × S = 3 × 3 = 9sq.m

(66 - 9) sq.m = 57 sq.m

(54 - 9) sq.m = 45 sq.m

Total area the shaded part covers = 57 sq.m + 9 sq.m + 45 sq.m = 111 sq.m

Answer 2

Step-by-step explanation:

area of shaded region = 22 ×3 + 18×3 +3×3

= 66 + 54 + 9

129m^2

area of whole fig = 22 ×18 = 396m^2

area of unshaded region = 396m^2-129m^2

267m^2 ans..
