The length of the rectangle is 24 cm and the width is 3 times less. Find the sides of a rectangle if its perimeter is equal to the perimeter of the given rectangle.

A rectangle is a rectangle with equal opposite sides and right angles.

The perimeter is the sum of all sides. For such a figure, it is determined by the formula:

P = 2a + 2b. Let’s find this value, for a rectangle whose length is 24 cm, and the width is 3 times less:

P = 2 * 24 + 2 * 24: 3 = 48 + 16 = 64 cm.

Find the sides of a square whose perimeter = 64 cm.

A square is a quadrangle in which all sides are equal and the corners are right.

The sum of its sides (Perimeter) is calculated by the formula:

P = 4a. Let’s express the side:

4a = 64. To find the second factor, divide the product by the first:

a = 64: 4 = 16 cm.
