Calculate the area of a square whose side length is equal to a third of 2 m 58 cm.

In order to solve this problem, we first need to find out what one side of the square is equal to, and then, proceeding from the fact that all sides of a square are equal to find out its area.
Since one side is exactly a third from 2m 56 cm, we need to determine this third. To do this, we do this:
2 meters 58 cm.This is exactly 258 cm. (1m = 100cm)
258/3 = 86 centimeters, the size of the sides of the square.
Next, we find out its area by multiplying the size of one side by the size of the other.
86 * 86 = 7396 square centimeters, square area.
Or in square meters;
0.86 * 0.86 = 0.7396 square meters, square area.
