The width of the rectangle is 3 cm. What is the length if its perimeter is 16 cm. Find the area of the figure.

Since the perimeter of the rectangle is 16 centimeters, the sum of its length and width will be:

16/2 = 8 cm.

We know that the width is 3 cm, so the length value will be equal to the difference between the sum of the sides and the width, namely:

8 – 3 = 5 cm.

To find the area of the shape, multiply the length of the rectangle by the width.

Will be:

3 * 5 = 15 cm2

Answer: The length of the rectangle is 5 cm. The area is 15 cm2
