Question

John made a triangle with all three sides the same length, 1 \frac{2}{3} ft. What is the perimeter of the triangle?

Answer 1

5 ft

Explanation:

If all sides are of the same length, we can multiply the value of one side by 3, because a triangle has three sides (and the perimeter is all sides added together), to find the perimeter.

`1(2)/(3)` × 3

`1(2)/(3)` can be rewritten as
`(5)/(3)`, so:

`(5)/(3)` ×
`(3)/(1)`

`= (15)/(3)`

The numerator & denominator share a common factor of 3, so:

5 ft is the final answer/perimeter.

hope this helps!
