Question

Your neighbor needs to put a fence around her front yard and a separate fence around her back yard. Her front yard is 65 feet long and 45 feet wide. Her back yard is 35 feet long by 45 feet wide.

How much fencing should she buy? (The fence is not attached to the house.)

160 feet
220 feet
380 feet
425 feet

Answer 1

Answer: Third Option is correct.

Explanation:

Since we have given that

Length of front yard = 65 feet

Width of front yard = 45 feet

Perimeter of front yard is given by

`2(Length+Width)\\\\=2(65+45)\\\\=220\ feet`

Length of back yard = 35 feet

Width of front yard = 45 feet

Perimeter of back yard is given by

`2(Length+Breadth)\\\\=2(35+45)\\\\=160\ feet`

Total fencing she should buy is given by

`220+160\\\\=380\ feet`

Hence, Third Option is correct.
