If the perimeter of a rectangle is 260 feet and the length is 30 feet more than the width, what are the dimensions of the rectangle?
~~~~~~~~~~~~~~~~~~`
Let W be the width, then the length is W+30.
W + (W+30) + W + (W+30) = 260,
4W + 60 = 260,
4W = 260-60 ---> 4W = 200 ---> W = = 50.
Answer. The wide is 50 ft. The length is 50+30 = 80 ft.
You can put this solution on YOUR website! 2L+2W = Perimeter
L = W+30 substitute for L in the equation above:
2(W+30)+2W = 260
2W+60+2W = 260
4W = 200
W = 50
and
L = 50+30 = 80
