Question

Anne decided to build a fence around her 15 feet long flower bed. How many feet of fencing should she buy if the width of the flowerbed is 4/5 the length?

Answer 1

`54` feet

Explanation:

Length of the flower bed
`=15` feet.

Width of the flower bed is
`(4)/(5)` the length.

So, width
`=(4)/(5)* 15=4* 3=12` feet.

To find the length of the fencing, we need to find the perimeter of the flower bed.

Perimeter of a rectangle
`=2(\textrm{length} + \textrm{width})`

So, perimeter of the flower bed
`=2(15+12)=2* 27 = 54` feet.

Hence,
`54` feet of fencing is required for the flower bed.
