Question

A rectangular room is

4
meters longer than it is wide, and its perimeter is
24
meters. Find the dimension of the room.

Answer 1

length = 8 ft

width = 4 ft

Explanation:

Let the width = x.

Then the length = x + 4.

perimeter = x + x + x + 4 + x + 4 = 4x + 8

4x + 8 = 24

4x = 16

x = 4

x + 4 = 4 + 4 = 8

Answer:

length = 8 ft

width = 4 ft
