Question

What is the distance around a triangle that has sides measuring 2 1/8 feet, 3 1/2 feet, and 2 1/2 feet?

Answer 1

The distance around the triangle is the perimeter of the triangle.
It is

`2 \, (1)/(8) + 3 \, (1)/(2) + 2 \, (1)/(2) \\ = 2+3+2+ (1)/(8) + (1)/(2) + (1)/(2) \\ = 7 + (1)/(8) + 1 \\ = 8 \, (1)/(8)`

Answer:
`8 \, (1)/(8) \, feet`
