Question

The area of the wall and a volume of a rectangular room is 96and 144. The logest rod fitted into the room is 13 m. What is the dimension of the room?

Answer 1

Here is the answer for your question


Given:

Area of 4 walls= 660 m²

Height (h)= 11 m

Let the width be = b m

Length (l)= 2b m

Area of 4 walls of a room = 2(l+b)×h

660 = 2 (2b+ b ) × 11

660 = 2(3b) ×11

3b = 660 / 11× 2= 60/2= 30

3b = 30

b= 30/3= 10

b= 10 m

L = 2b = 2× 10= 20 m

L = 20 m

Area of ceiling = l × b

Area of ceiling= 20 × 10 = 200 m²

Hence, the area of ceiling is 200 m²
