Question 783231: the perimeter of a rectangle is 82 cm. The length is 6 cm longer than the width. Find both lengths

You can put this solution on YOUR website!
Width = x
Length = x + 6
Perimeter = 2*width + 2*length
82 = 2x + 2(x + 6)
82 = 2x + 2x + 12
Collect like terms.
4x = 82 - 12
4x = 70
x = 17.5 cm
Width = 17.5 cm
Length = 23.5 cm
Hope this helps.
