The length of a rectangle is 5 m longer than its width. If the perimeter of the rectangle is 30 m. What is its area?

Answer 1

If the width is x, then the length is x + 5. The perimeter is just 2x + 2(x + 5) = 30.

So 2x + 2x + 10 = 30

4x = 20

So width = 5 m and length is 10 m

The are is just length*width so Area = 50 m²
