Question

if height of square room is 6m and area of floor is 87 meter square find the area of four walls.

Answer 1

Answer:

Step-by-step explanation:

Area of floor of a square room=87m^2

Or l^2=87

Or, l=√87 =9.327m

Height of wall=6m

Therefore area of 1 wall=6×9.327=55.962m^2.

Hence area of 4 walls=4×55.962=223.848m^2
