Answer:
Explanation:
The perimeter of the rectangular yard is given by the formula P = 2l + 2w, where l is the length and w is the width.
We have l = 75 1/2 feet and w = 65 feet.
First, we need to convert the mixed number 75 1/2 to an improper fraction:
75 1/2 = (75 × 2 + 1)/2 = 151/2
So, we have:
P = 2(151/2) + 2(65)
P = 303/2 + 130
P = 563/2
To simplify the answer, we can convert the mixed number back to a mixed number:
P = 281 1/2 feet
Therefore, Bruce needs 281 1/2 feet of fencing to install around his rectangular back yard.
