The fuctoin that demenstrates this problem is 32=24+0.05x so all you have to do is solve for xyou would subtract 24 from bolth sides geting 8=0.05x then divide bolth sidews by o.o5 wich you get 160=x so the answer is 160.
All you have to do is plug in the value of X in each expression for the sides of the triangle. Then after you figure out the values for the sides of the triangle in feet. Add the sides together to find the perimeter of the triangle.
