a rectangular courtyard measures 20 feet by 15 feet and contains an 8.5-foot square flower garden.

Question

The remaining space is covered by grass. What is the area of the courtyard that is covered by grass

Answer 1

1. The area of the rectangle is LW, length times width or 300 sq ft

2.  The area of the square is 8.5 x 8.5 or 72.25 sq ft

3. Subtract the area of the square from the area of the rectangle 300-72.25=277.75 sq ft

277.75 is the area of the grass
