Question 396789: The length of a rectangle is 12 cm more than it's width. Find the area of the rectangle if its perimeter is 100 cm. Answer by solver91311(24713) (Show Source):
Let represent the width of the rectangle. Then represents the length. The perimeter of a rectangle is given by 2 times the length plus 2 times the width, so:
Solve for to get the width. Add 12 to get the length. Multiply the length times the width to get the area.
