Answer:
<h2>The question we need to answer is what is the perimeter of the arena</h2>
Step-by-step explanation:
The question we need to answer is what total length of plank did the farmer ordered for the arena.
to solve for the length of plank to cover the arena we need to solve for the perimeter of the arena.
given data
length L= 115 1/4 ft = 115.25ft
width W= 63 1/2 = 63.5ft
perimeter= 2L+2W
perimeter= 2(115.25)+2(63.5)
perimeter= 230.5+127
perimeter= 357.5ft
This means that the farmer ordered a total length of 357.5ft of plank
28=-2-5x
30=-5x
30/-5=-5x/-5
-6=x
B because the other 3 graphs don’t fit the equation
