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

Answer:

20 units

Step-by-step explanation:

s = 8

Perimeter = s + s + $\frac{1}{2}*s$

                $= 8 + 8 + \frac{1}{2}*8$

                = 8 + 8 + 4

               = 20 units

Answer 2

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