Question

a rectangular hall 12 metre long and 10 M broad is surrounded by a verandah 3M wide find the area of the verandah​

Answer 1

Answer:

96 m²

Step-by-step explanation:

Area of hall = 12m × 10m = 120 m²

Allowing for 3m width of verandah on each side, the rectangle inside the verandah has:

length = 12m - 3m - 3m = 6m

breadth = 10m - 3m - 3m = 4m

So area inside verandah = 6m × 4m = 24 m²

Area of verandah = area of hall - area inside verandah

     = 120 m²  -  24 m²

     = 96 m²
