Question

Find the perimeter in simplest form and explain your work

Answer 1

`perimeter \: of \: the \: triangle \\ = 2 (3)/(8) +2(3)/(8) + 2 (3)/(8) \\ = 3 * 2 (3)/(8)\\= 3 * (19)/(8) \\ = (57)/(8) \: yd \\ = 7 (1)/(8) \: yd`

57/8 yards is the right answer.

Answer 2

9514 1404 393

Answer:

7 1/8 yd

Explanation:

The perimeter is the sum of the three side lengths. They are all the same, so we can use multiplication to find their sum.

P = 3·(2 3/8 yd) = 6 9/8 yd . . . . . 9/8 = 1 1/8

P = 7 1/8 yd

The perimeter is 7 1/8 yards.
