Question

Thelength is 15m, breadth is 7.5m and height of room are 5m. What is the area of the room with four walls?

Answer 1

Hii friend,

Length of the room = 15 m

Breadth of the room = 7.5 m

Height of the room = 5 m

Therefore,

Area of four wall of the room = 2(L+B) × H


=> 2 ( 15+7.5) × 5

=> 2(22.5) × 5

=> 45 × 5

=> 225 m²

Hence,

The area of four faces of the wall is 225 m²

HOPE IT WILL HELP YOU..... :-)

Answer 2

Area of four walls = perimeter × height
___________________

Area of four walls = 2(15+7.5) × 5

Area of four walls = 2×22.5 ×5


Area of four walls = 10×22.5

Area of four walls =225m²



I hope this will help you
