Answer:
70
Step-by-step explanation:
<u>Basic Concept: Geometry</u>
<u>Formula:</u>
<u>Area of a polygon = </u><u></u>
where p = perimeter and a = apothem
In this problem we are given the area and the apothem and we need to find the perimeter
To do so we want to plug what we are given into the formula and solve for the missing piece.
We are given the area (350) and the apothem (10)
So in the formula we would plug in 350 for the area and 10 for "a"
We would then have
<u>Basic Concept: Algebra</u>
Now we use basic algebra to solve for p (perimeter)
step 1 multiply each side by 2
now we have 700 = 10p
Step 2 divide each side by 10
700/10=70
10p/10=p
we're left with p = 70
So we can conclude that the perimeter is equal to 70
