So we have P = 60m, L = 20m. Guess this is a rectangle. The equation for the perimeter P of a rectangle is $$P = 2L + 2W$$, where L = length, and W = width. Here, we allready know P and L => we have the equation$$60 = 2*20 + 2*x$$. Now, we will solve for x, which is the width of the rectangle and we obtain$$x = (60-40)/2 = 20/2 = 10$$, which means that the dimensions of the dance floor is L*W = 20*10.
