| The two rectangles have the same area. The length of the first is 8cm, and its perimeter is 40 cm. The width of the second is 12.8 cm. Find the length of the second rectangle

The length of the first rectangle is 8 cm.

The width of the first rectangle is x cm.

2 * (8 + x) = 40

8 + x = 20

x = 12

The area of the first rectangle = 8 * 12 = 96 cm.

The area of the second rectangle is also 96 cm.

The second rectangle is 12.8 cm wide.

The length of the second rectangle = 96 / 12.8 = 7.5 cm.
