Answer The answer is C

Everywhere there is a (t) plug in a number from the time data, its better to use a number that isnt 0 or 1. Once you plug in a number from the time data solve the equation and see if it equals to the corrosponding height.

h(t)=-5.03(1.5)^2 + 10.22(1.5) +2.99 = 7

                 (t)                       (t)                (h)

Notice how the underlined numbers correspond with each other on the given data.

(t) 1.5

(h) 7.0

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
