Question 787188: If a rectangle has a length the is 4cm more than its width, and the perimeter is 28cm, find the dimensions of the rectangle

Width = x
Length = x + 4
Perimeter = 2*width + 2*length
28 = 2(x) + 2(x + 4)
28 = 2x + 2x + 8
Collect like terms
4x = 28 - 8
4x = 20
x = 5
Width = 5 cm
Length = 9 cm.
Hope this helps.
