Answer:
54 ft
Step-by-step explanation:
Length of the rectangular flowerbed = 15 ft
Width of the rectangular flowerbed = 4/5 of the length
= 4/5 × 15
= (4*15)/5
= 60/5
= 12
Width of the rectangular flowerbed = 12 ft
How many feet of fencing should she buy
Perimeter of the rectangular flowerbed = 2(length + width)
= 2(15ft + 12ft)
= 2(27ft)
= 54 ft
Perimeter of the rectangular flowerbed = 54 ft
She should buy 54 ft of fencing
