Word problems I'm not so good with anyone want to give me a hand I would greatly appreciate it.
A farmer in Texas is building a fence in the shape of a right triangle around some of his property. He knows the two shorter sides to be 9 ft. long and 10 ft. long. If the farmer must pay $10 per foot of wood, how much will he need to spend on the longest side of the fence? Round your answer to the nearest dollar.

x is longest side. since right triangle, 9² + 10² = x²
x² = 181
x = 13.45 ft
@$10/ft, $134.50 ≈ $135.

Using the pythagorean theorem, the long side would be
___________
V 10^2+9^2 or the square root of 181 which is approx.13.5 ft. the cost would be $135.
