Use the image to answer the question.
A composite shape is drawn with a rectangle and a square. All lines are straight and all corners are marked as right angles. The shape is made with a vertically aligned rectangle 8 yards in length and 7 yards in width. A horizontally aligned rectangle 3 yards wide and of unknown length is removed from the bottom left corner of the original rectangle. The remaining width along the bottom right is 3 yards.
Solve the following problem: A town has a swimming pool shaped as in the diagram.
What is the area of the swimming pool in square yards?
(1 point)
The area of the swimming pool can be calculated by finding the total area of the original shape and then subtracting the area of the removed rectangle.
Area of original shape = Length x Width
= 8 yards x 7 yards
= 56 square yards
Area of removed rectangle = Length x Width
= 3 yards x 3 yards
= 9 square yards
Area of swimming pool = Total area - Area of removed rectangle
= 56 square yards - 9 square yards
= 47 square yards
Therefore, the area of the swimming pool is 47 square yards.
