Question

The area of a square is equivalent to the area of a rectangle. If the side lengths of the rectangular three units and 12 units what is the perimeter of the square?

Answer 1

Answer:

Step-by-step explanation:

If the side lengths of the rectangle are 3 and 12, then the area, length times width, is 36.

If the area of the square is equivalent to the area of the rectangle, then

$36=s^2$ which is the formula for the area of a square.  Take the square root of 36 to get that each side of the square is 6 inches long.  

Since a square has 4 sides, we get that the perimeter of that square is 4 * 6 which is 24 inches.
