Question

The length of a rectangle is 3 cm longer than its width. if the perimeter of the rectangle is 46 cm , find its area.

Answer 1

A) L = W + 3
B) 2L + 2W = 46
Putting equation A into B
2 * (W+3) + 2W = 46
2W + 6 + 2W = 46
4W = 40
Width = 10
Length = 13

Area = Length * Width
Area = 13 * 10
Area = 130 square centimeters
