The perimeter of the rectangle is 54m and the length is 18m, what is its area?

To solve this problem, recall the formula for the area of a rectangle. The area of the rectangle is equal to the product of the length and the width. S = a * b, where a is the length and b is the width. 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 + 18) * 2 = 54;

b + 18 = 54/2;

b + 18 = 27;

b = 27-18;

b = 9 cm.

Let’s calculate the area of the rectangle.

S = 9 * 18 = 162 sq. Cm.

Answer: 162 sq. Cm.
