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.
