Question

the length,breadth and height of a room are 6m,5.4m and 4m respectively.
find the area of its four walls and of its roof​

Answer 1

Answer:

Length of the room = 6 m

Breadth of the room = 5.4 m

Height of the room = 4 m

(i) Area of four walls = 2(L+B) x H

= 2(6 + 5.4) x 4 = 2 x 11.4 x 4 = 91.2 m2

(ii) Area of the roof = L x B = 6 x 5.4 = 32.4 m2

Step-by-step explanation:

Answer 2

ATQ (according to the question)

Length= 6m

Breadth= 5.4m

Height= 4m

So the area of its 4 walls = 2(l+b)h

= 2(6+5.4)4

= 8(11.4)

= 91.2m²

area of roof = L×B

= 6*5.4

= 32.4m²

Here's your ans
