Question

The field at Harrington Middle School is 70 yards long and has a diagonal measure of 84 yards. What is the perimeter of the triangular field?

Answer 1

Answer:

200.43 yds

Step-by-step explanation:

84 x 84 = 7,056

70 x 70 = 4,900

7,056 - 4,900 = 2,156

$\sqrt{2156}$ = 46.43

84 + 70 + 46.43 = 200.43 yds
