Question

Darla is building a new desk. To make sure she had made a square corner, she measures 10ft. from the corner along one edge and 5ft. from the corner along the other edge. How long should the diagonal be between those two points if the corner is a right angle?

Answer 1

8.15 is what I keep getting

Answer 2

\[d=\sqrt{10^2+5^2}\] where d = the length of the diagonal. :)

Pic attached to explain why.
