Question

The isosceles triangle has two sides with the same length. The base is one-half the length of a side. The expression which represents the perimeter, the distance around the triangle, is s + s + one-half s. What is the value of this expression if s = 8?

A triangle with 2 sides with length s.

Answer 1

20
S=8
1/2s=4
8+8+4=20
Answer is 20

Answer 2

20 units

Explanation:

s = 8

Perimeter = s + s +
`(1)/(2)*s`

`= 8 + 8 + (1)/(2)*8`

= 8 + 8 + 4

= 20 units
