A right triangle has legs of 2 feet and 18inches. What is the perimeter of the triangle in inches?

Three sides to a triangle, let's call them a, b and c.

The perimeter is a+b+c

a=2ft=24in

b=18in

c=?

Pythagoras' Theorem is a²+b²=c ²

a²+b²=c²

24²+18²=c²

576+324=c²

900=c²

√900=c

30=c

a=24in

b=18in

c=30in

perimeter=a+b+c

perimeter=24+18+30

perimeter=42+32

perimeter=72

72in=6ft
