The width of the rectangle is half its length. Calculate the perimeter and area of this rectangle

The width of the rectangle is half its length. Calculate the perimeter and area of this rectangle if it is known that its width is 5 cm.

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 the length of the rectangle.

5 * 2 = 10 cm.

Let’s calculate the area and perimeter of the rectangle.

S = 5 * 10 = 50 sq. Cm.

P = 2 * (5 + 10) = 2 * 15 = 30 centimeters.

Answer: 50 sq. Cm. 30 cm.
