You are bidding on a new job to Zamboni the ice on a local hockey rink. There are eight rinks in the arena. The rink is 200 feet by 80 feet. The Zamboni cleans the ice with a blade length of 25 inches. The Zamboni moves around the rink at about 3 miles per hour and can only clean moving along the long side of the rink. It cannot maneuver on the short side.​

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral

30005

yes ok
