Question

The length of a rectangle is 4 cm longer than its width. If the perimeter of the rectangle is 44 cm, find its area

Answer 1

Length is w+4 for width w

 

2w + 2(w+4) = 44

2w + 2w+ 8 = 44

4w + 8 = 44

4w = 36

w =9

 

width is 9, length is 13

perimeter is 9+9+13+13 = 18 + 26 = 44.

Area is 9 x 13 = 107 square centimeters
