Question

a rectangular field measures 10 yards by 24 yards. What is the distance, d, from one corner to the opposite corner?

Answer 1

Using the Pythagorean theorem to solve this, d=26, here's how.
a^2+b^2=c^2
plug in the numbers you already have
10^2+24^2=d^2
100+578=676
676=d^2
take the square root of that
√676=26
d=26
