The shorter leg of a right triangle is 6ft shorter than the longer leg. The hypotenuse is 6ft longer than the longer leg. Find the side lengths of the triangle.

Length of the longer side =

24

m

Length of the shorter side =

18

m

Length of the hypotenuse =

30

m

Explanation:

From the data given, we can write:

Length of the longer side =

x

Length of the shorter side =

x

−

6

Length of the hypotenuse =

x

+

6

The Pythagorean Theorem states the the square of the hypotenuse is equal to the sum of the squares of the other two sides. Hence.

Since the length has to be a positive integer, the length of the longer side is

24

m

.

Hence:

Length of the longer side =

24

m

Length of the shorter side =

18

m

Length of the hypotenuse =

30

m

To verify, we apply the Pythagorean Theorem:
