215.6 meters

Step-by-step explanation:

Formula of a polygon: A= 1/2ap

a = apothem

p = perimeter

Since the polygon has 7 sides, you need to multiply 7 by 7.7 (side length) to find the perimeter which would be 53.9

A= 1/2 x 8 x 53.9

A = 215.6 meters

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
