Given : Figures
24 m by 16 m and then 2 m left inside each side to create path
To Find : Shaded area
Solution:
area of the shaded portion = outer area - inner area
outer area = 24 x 16 = 384 m²
inner dimensions 24 - 2 - 2 = 20 m by 16 - 2 - 2 = 12 m
Inner area = 20 x 12 = 240 m²
area of the shaded portion = 384 - 240 = 144 m²
area of the shaded portion = outer area - inner area
outer area = 36 x 30 = 1080 m²
Inner area = 25 x 25 = 625 m²
area of the shaded portion = 1080 - 625 = 455 m²
