| **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.
