Question

The area of four walls of a room is 660 and its length is twice its breadth.if the height of the room is 11 cm then find area of the floor

Answer 1

Hi ,

Let breadth of the room = b cm

Length = L = 2b

Height = H = 11

Area of four walls of the room

= 660

2( L + b ) H = 660

2 ( 2b + b ) = 660

2 × 3b = 660

b = 660/6

b = 110 cm

Therefore ,

L = 2b = 2 × 110 = 220 cm

Area of the floor = L × b

= 220 × 110

= 24200 cm²
