The area of the rectangle is 15 cm2 the width is 3 cm, find the perimeter of the rectangle?

1) Find the length of the rectangle, finding out the quotient known to us by the condition of the area of the rectangle (15 square centimeters) and its width (3 centimeters).

15/3 = 5.

The length of the rectangle is 5 centimeters.

2) Now, using the data we obtained in the previous action about the length of the rectangle and known by the condition – about the width, we determine what its perimeter is. To do this, add the length and width values and multiply the result by 2.

(5 + 3) * 2 = 16.

Answer: The perimeter of the rectangle is 16 centimeters.
