You can put this solution on YOUR website! What is the area of a rectangle if the perimeter is 44in. And the length is 4x in. And the width is x+ 7 in.
------
Perimeter = 2(length + width)
44 = 2(4x + x+7)
22 = 5x + 7
5x = 15
x = 3
----
length = 4x = 12
width = x+7 = 10
------
Area = 10*12 = 120 in^2
