Question

A verandah 2 m wide is constructed all around a room of dimensions 8 m X 5 m. Find the area of the verandah

Answer 1

Length of outer rectangle = 8 + 2 + 2 =12m

Breadth of outer rectangle = 5 + 2 + 2 = 9m

Area of outer rectangle = l x b = 12 × 9 = 108m²

Length of inner rectangle = 8m

Breadth of inner rectangle = 5m

Area of inner rectangle = l x b = 8 × 5 = 40m²

∴ Area of the verandah = (Area of outer figure) – (Area of inner figure)

= 108 – 40 = 68m²
