The length of a rectangle is 12m longer than the width. If it has a perimeter of 104m. Calculate for the area of the rectangle
Let the width of the rectangle be x meters.
Therefore, the length of the rectangle is x + 12 meters.
Perimeter of a rectangle = 2(length + width)
104 = 2(x + x + 12)
104 = 4x + 24
4x = 80
x = 20
So, the width of the rectangle is 20m and the length is 20m + 12m = 32m.
Area of a rectangle = length x width
Area = 20m x 32m
Area = 640 square meters
Therefore, the area of the rectangle is 640 square meters.
