Question

In a rectangle, the length is 5 more than three times the width. The perimeter is 250cm. Determine the length of each side.

Answer 1

l = 95 cm

w = 30 cm

Explanation:

w = width

5+3w = length

P = 2l + 2w

250 = 2(5+3w) + 2w

250 = 10 + 6w + 2w

240 = 8w

w = 30

5 + 3(30) = length

l = 95
