Answer:
$328.95
Step-by-step explanation:
By the Pythagorean theorem, the diagonal of the garden has a length that is the root of the sum of the squares of the side lengths:
d = √(77² +36²) = √7225 = 85
Then the cost of the fence is the product of this number of feet and the cost per foot:
(85 ft)·($3.87/ft) = $328.95
