David must install fencing around a lot that is shaped like a right triangle. The side of the lot that runs east-west is 200 ft long. The side of the lot that runs north-south is 125 ft long. Calculate how many feet of fencing he will need to surround the entire lot. If necessary, round your answer to the nearest whole.

Respuesta :

1. Observe problem

I think 200ft and 125 ft are both sides, so:

sqrt(200^2+125^2) is 25sqrt{89}

which is

235.84952
