Question

What is the distance around a triangle that has sides measuring 21/8 feet, 31/2 feet and 21/2 feet?

Answer 1

Add all of the sides together. Make sure to use a common denominator because you are adding fractions. Don't forget your unit label (feet)

`(21)/(8)` +
`(31)/(2)` +
`(21)/(2)`

`(21)/(8)` +
`(124)/(8)` +
`(84)/(8)`

`(229)/(8)` feet
