Question

The figure shows an aerial view of a playground. If David runs around the field three times, he covers a distance of ___yards.

Answer 1

Answer: 648

The person above me is correct. But some programs (edmentum plato) require the answer to be to the nearest integer. So the answer is 648.

Answer 2

The first thing we must do for this case is to find the perimeter of the figure.
We have then that the perimeter is:
P = ((35) * (280/180) * pi) + 45
P = 216.04 yards.
Then,
As David runs the field three times then:
d = 3 * P
d = 3 * 216.04
d = 648.12 yards.
Answer:
he covers a distance of 648.12 yards
