2) the required perimeter is:
3) the required area is:
Split it into three rectangles, find the area of each one and add them together. You can split it multiple ways but the way I did it, you would end up with this: 10*2+2*2+2*2
now... let's see
"<span>m varies directly as the square root of y, inversely as p², and directly as n"
</span>
<span>
now, let's quadruple "y", multiply "n" by 5 and "p" by 3
