Because we are dealing with area, we have to square the difference of the 2 polygons.40 / 15 =
<span>
<span>
<span>
2.6666666667
</span>
</span>
</span>
<span>
<span>
<span>
2.6666666667^2 = </span></span></span>
<span>
<span>
<span>
7.1111111111
</span></span></span>
<span><span><span>
</span>
</span>
</span>
So, the 40 yard polygon has <span>
<span>
7.1111111111</span>times the area of the 15 yard polygon.

Parenthesis, then exponents, then subtraction.
Answer:
Step-by-step explanation:
The area of a rectangle is given by 
, where 
is the length of the rectangle and
