Question

A rectangular field is 40 yards long. If you ran diagonally across the field, you would run 50 yards. How many yards wide is the field?

Answer 1

Try solving for x using the Phythagorean Theorem, as we have a right triangle here.

Answer 2

a^2+b^2=c^2
so...
40^2 + 50^2= c^2
therefore...
1,600+2,500= 4,100^2
take the square root of 4,100 and your answer would be....

.....64.03
