What is the perimeter of a rectangle if its length is 7 meters and the width is 4 meters less?

To solve this problem, remember that the perimeter of a rectangle is the sum of the lengths of all its sides. Since in a rectangle the opposite sides are equal, then P = 2 * (a + b), where a is the length, b is the width. Let’s calculate what the width of the rectangle is.

b = 7 – 4 = 3 meters.

Let’s calculate the perimeter of a rectangle with sides of 7 meters and 3 meters.

P = 2 * (3 + 7) = 2 * 10 = 20 meters.

Answer: 20 meters.
