For:
Assume all values are in inches.
L=length of rectangle
W=width of rectangle
P=perimeter of rectangle
P=L + W + L + W
The problem states:
P=78
L=W + 3
Substitute the above values into the perimeter equation.
Suppose that the length of a rectangle is 3 inches longer than the width and that the perimeter of the rectangle is 78.
Set up an equation involving only W, the width of the rectangle.
