What is the perimeter of a square whose area is equal to the area of a rectangle with sides of 9 cm and 4 cm?

Let’s find the value of the area of ​​this rectangle, for this we need to multiply the value of the width of this rectangle by the value of the length of this rectangle:

4 * 9 = 36 cm2 – the value of the area of ​​this rectangle;

find the length of the side of the square, for this you need to extract the square root of the value of the area of ​​the square:

√36 = 6 cm – this is the side length of this square;

Find the value of the perimeter of this square, for this you need to multiply the length of the side of the square by four:

6 * 4 = 24 cm – the value of the perimeter of this square.

Answer: 24 cm is the value of the perimeter of this square.
