Elise built a rectangular vegetable garden that is 999 feet long and has an area of 72 square feet.

What is the perimeter of Elise's vegetable garden?

Perimeter of a rectangle=2 (long) + 2 (width)

1) we calculate the width.

area=long x width

dа ta:

area = 72 ft².

long=9 ft

72 ft²=9 ft * width

width=72 ft²/9 ft=8 ft.

2) we calculate the perimeter.

perimeter=2 (9 ft) + 2 (8 ft) = 18 ft + 16 ft=34 ft.

Answer: the perimeter of Elise's vegetable garden is 34 ft.
