The length of the rectangle is 18 m; the area of the rectangle is 144 m; the square is the width

The length of the rectangle is 18 m; the area of the rectangle is 144 m; the square is the width of the rectangle and the perimeter of the rectangle.

First you need to find the width of this rectangle.

Since we know the value of the area and the length of the figure, for this we divide the area by the length.

The result will be:

144/18 = 8 meters.

To find out the perimeter of a rectangle, we add the value of the known length and the found width, and then multiply the result by 2 equal parts.

Thus, we get:

(8 + 18) * 2 = 26 * 2 = 52 meters.

Answer: The width is 8 meters, the perimeter is 52 meters.
