Question

6 A rectangular room is 2 m longer than it is

wide. Its perimeter is 70 m. If the width of
the room is w m, express its length in terms
of zo. Hence find the width of the room.

Answer 1

W = 16.5 meters

Explanation:

let w be the width and then the length is w+2

Perimeter = 70 = 2w + 2(w+2)

70 = 2w + 2w + 4

4w = 66

w = 16.5 meters
