Question

A class room is 11m long 8m wide and 5m high find the area of floor and four walls

Answer 1

Answer:

hey mate right answer is here.

Step-by-step explanation:

Given,

length = 11 m

breadth =  8 m

height = 5 m

We know,

Area of floor = Area of rect.

                    = l*b

                    = 11*8

                    = 88 m

Area of 4 walls = 2(l+b)h

                         = 2(11+8)*5

                         = 2 * 19 * 5

                         = 190 m²

Answer 2

Answer:

Given

length (l) = 11m

breadth (b) = 8m

Height (h) = 5m

Area of floor = I × b

===> 11 × 8

===> 88m

Area of 4 walls = 2(l+b)h

===> 2( 11 + 8 ) 5

===> 2 ( 19 ) 5

===> 2 × 95

===> 190m²
