Question

If the length, breadth and height of a rectangular room are 6m, 5.2 m and 4.5 m respectively then area of its four walls =​

Answer 1

SOLUTION

It is given that ,

Length of the room = 6m

Breadth of the room = 5.2m

Height of the room = 4.5 m

Are of four walls

= 2 ( l + b ) × h

= 2 ( 6 + 5.2 ) × 4.5

= 2 × 11.2 × 4.5

= 102.80

so, the area of four is 102.80 msq

hope this answer will helps you.

Answer 2

i} A of 4 walls = 2(l+b)*h-------->2(6m+5.2m)*4.5m--------->22.4m*4.5m

 A of 4 walls = 100.8 m^2
