The area of the rectangle is 56 m2, and the width is 4 m. Find the area of the square, the perimeter of this rectangle.

To solve this problem, you first need to determine the length of this rectangle.

To do this, its area should be divided by a known width.

In this case, we get:

56/4 = 14 cm.

Find the perimeter of the rectangle.

To do this, we determine the doubled amount of its parties.

We get:

2 * (14 + 4) = 2 * 18 = 36 cm.

Find the side of the square.

To do this, divide the resulting perimeter by the number of sides.

36/4 = 9 cm.

Find the area of the square.

We multiply the two sides of the square with each other.

9 * 9 = 81 cm ^ 2.

Answer: 81 cm ^ 2.
