Question

The three sides of a right triangle are in the ratio of 3:4:5. If the perimeter of the triangle is 48 inches, what is the length of the longest side?

Answer 1

Answer:

here's the answer

Step-by-step explanation:

let the sides be 3x, 4x, 5x.

perimeter of a triangle = sum of all the sides

48=3x+4x+5x

48=12x

x=48/12

x=4

3x=3X4=12

4x=4X4=16

5x=5X4=20

length of the longest side =20
