Question

Eli has two boards that measure 1.5 feet and 2 feet long. He needs a third board to

form a right triangle with the boards. What length should the third board be so a right
triangle is formed? Round to the nearest tenth.

Answer 1

The third board should be 2.5 feet long.

If you use the pythagorean therom to find the third board as the hypotenuse.

1.5^2 + 2^2 = c^2
6.25=c^2
sqrt both sides
2.5=c
