The width of the rectangle is 5 m, its length is 2 times its width. What is the perimeter of the rectangle? What is its area?

In order to find the area of a rectangle, you need to find the product of its two adjacent sides. S = a * b, where a is the length and b is the width.
The perimeter of a rectangle is twice the sum of its two adjacent sides. P = 2 * (a + b), where a – length, b – width. Let’s calculate the length of the rectangle.

a = 5 * 2 = 10 m.

Let’s calculate the perimeter of the rectangle.

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

Let’s calculate the area of the rectangle.

S = 5 * 10 = 50 sq.m.

Answer: 30 m, 50 sq.m.
