Question

A verandah 4 m broad runs round a hall, which is 20 m long 15 m wide. Find the area of verandah

Answer 1

Answer:

given that,

length of verandah = 20m

Breadth of verandah = 15m

area of the verandah = lxb = 20x15 = 300m²

therefore, 300m² is the area of the verandah

hope it helps you

Answer 2

Answer:

area of hall,

length= 20m

breadth = 15m

area= 20m × 15m= 300m^2

area of hall with verandah

length = 20+4+4= 28m

breadth= 15+4+4= 23m

area= 28×23 = 644m^2

area of verandah= 644m^2 - 300m^2

= 344m^2.
