Question

The ratio of the lengths of 3

sides of a triangle is 2: 3:5, and
the perimeter is 80 inches.
What is the length of the
shortest side of the triangle?

Answer 1

Explanation:

the ratio of the side lengths is

2 : 3 : 5

that means we are dealing with 2+3+5 = 10 length units of the total circumference.

so,

80 in = 10 length units

1 length unit = 80/10 = 8 in.

so, the shortest side is 2×8 = 16 in.

the middle side is 3×8 = 24 in.

the longest side is 5×8 = 40 in.
