The side of the square is 8 cm. The sum of the sides of a rectangle with a length

The side of the square is 8 cm. The sum of the sides of a rectangle with a length of 10 cm is equal to the sum of all sides of the square. What is the width of the rectangle?

First of all, let’s calculate the sum of all sides of the square, for which we will increase the known length of its side by 4 times. So, we get:

P = 4 * 8 = 32 (cm).

By the condition of the problem, we know that the sum of the sides of a given square is equal to the sum of the sides of a rectangle, the length of which is 10 cm.Let us determine its width by dividing the known perimeter in half, and subtracting the length from the result obtained:

32: 2 = 16 (cm).

16 – 10 = 6 (cm).

Answer: The width of the rectangle is 6 cm.
