The area of the square whose side length is 4 cm is
equal to the area of the rectangle whose length of one of its sides is 1 cm.
What is the perimeter of the rectangle?
After squaring all sides, we can calculate the area as follows:
Since we are given that the area of the square equals the area of the rectangle , we will write an equation with an unknown since we are only given one side length of the parallelogram:
In other words, we now know that the length and width of the rectangle are 16 and 1, and we can calculate the perimeter of the rectangle as follows:
