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
The equivalent expressions are 3(6x - 3) = 72 and 18x - 9 = 72
<h3>Equations and expressions</h3>
Given the equation below as shown;
3/5(30x - 15) = 72
Expand
3/5(30x) - 3/5(15) = 72
90x/5 - 15/5 = 72
3(6x - 3) = 72
Expand
18x - 9 = 72
Hence the equivalent expressions are 3(6x - 3) = 72 and 18x - 9 = 72
