The side of an equilateral triangle is 8 cm. Find the area of a square whose perimeter is equal to the perimeter of this triangle.

To solve this problem, you first need to determine the perimeter of the triangle.

Since it is equilateral, we multiply the side length of the figure by their number.

8 * 3 = 24 cm.

Find the side length of the square.

We divide the previously found perimeter by the number of sides of the figure, namely 4.

Will be:

24/4 = 6 cm.

Find the area of the square.

To do this, we multiply the two sides of the square with each other.

6 * 6 = 36 cm2

Answer: The area of the square is 36 cm2
