The perimeter of an equilateral triangle is 24cm. The length of the rectangle is equal to the side

The perimeter of an equilateral triangle is 24cm. The length of the rectangle is equal to the side of this triangle. The width is half the length. Find the perimeter of the rectangle.

In an equilateral triangle, all sides are equal, we find the length of one side if the perimeter is 24 cm.

P = 3 * a.

24 = 3 * a.

a = 24: 3.

a = 8 cm is the side of the triangle and, according to the condition of the problem, the length of the rectangle.

Find the width of the rectangle, it is equal to half the length, and the length is 8 cm.

8: 2 = 4 cm – the width of the rectangle.

Find the perimeter of a rectangle with sides of 8 cm and 4 cm.

P = 2 * (a + b).

P = 2 * (8 + 4).

P = 2 * 12.

P = 24 cm.

Answer: A rectangle with sides of 8 cm and 4 cm, the perimeter is 24 cm.
