Find the area of the rectangle. You can find the area of a rectangle with the following formula:
w = width, and l = length.
Plug in your width and length:
The area of the rectangle is 200 square centimeters.
The area of a square is also given by width * length. Multiply the sides together:
The area of a square is 4x^2.
Because you're cutting away the square from the rectangle, you will subtract the area of the square from the area of the rectangle. The following equation will be your answer:
