Answer:
-28
Step-by-step explanation:
2xy=2(7)(-2)=14(-2)=-28
The area of a polygon is <span>A=perimeter×apothem÷2
</span>you know <span>A=500</span><span> and apothem = 10\
</span>
<span>500=<span><span>P×10/</span>2
</span></span>you should get that the perimeter is 100<span> from the algebra
</span>
<span>part 1 is 100, the perimeter is 100
</span>
The 100 * 7.95
