# Square showcase area 64m3. Find out its perimeter.

March 25, 2021 | education

| Let the side of the showcase be equal to a, then we write its area by the formula:

S = a * a;

S = a²;

Let’s find the side of the showcase a, based on the fact that the area of the showcase is 64 m2:

a² = 64;

a = √64;

a = 8 m.

Since the perimeter of the figure is the sum of all its sides, we will find the perimeter of the showcase:

P = 4 * a, where P is the perimeter of the showcase;

P = 4 * 8;

P = 32 m.

Answer: the perimeter of the showcase is 32 meters.
