Question

a rectangular hall measuring 24m * 16m is surrounded by a verandah 1.5m wide . area of the verandah is ​

Answer 1

Step-by-step explanation:

area of hall = l×b

= 24×16

= 384m²

area of rectangular hall including verandah = (l+1.5)×(b+1.5)

= (24+1.5)(16+1.5)

= 25.5 × 17.5

= 446.25m²

area of verandah = 446.25 - 384

= 62.25m²

Answer 2

answer= 62.25

explanation:

area of hall=24*16

=384

sides including verandah=24+1.5 and 16+1.5

area including verandah=25.5*17.5

=446.25

actual area of verandah=area including verandah-area of hall

= 446.25-62.25

=62.25
