Question

A rectangular hall 12m long and 10m broad is surrounded by a verandah, 2m wide. Find the area of the verandah.

Answer 1

Find the area of hall = 12 x 10 = 120m²

Now we will find the area of total ie hall and varandah

So length = 12 + 2 = 14

width = 10 + 2 = 12

area = 14 x 12 = 168m²

We know total area and hall area. So to find varanda area only

168 - 120 = 48m²

Answer 2

Answer: 104

Step-by-step explanation: 12 x 10 is 120.

New l and b.

L: 12+2+2=16

B: 10+2+2=14

Now , 16x14 is 224 (area of rectangular hall including the veranda)

Now., 224-120=104 is the answer.
