Answer:
Area of flower bed = 189 square feet
Explanation:
The formula for the area of a rectangle is given by:
A = lw, where
- A is the area in square units,
- l is the length,
- and w is the width.
Thus, we can plug in 21 for l and 9 for w in the rectangle area formula to find A, the area of the rectangular flower bed in square feet:
A = 21 * 9
A = 189
Thus, the area of the rectangular bed is 189 square feet.
