w=width
It can represent formulas like A=L×W etc...
P = 2 (L + W) and A = L x W
21% Area = length*width Let Aoriginal represent the original area and Aheated represent the area of the rectangle after heating. Let l and w represent the original length and width of the rectangle. Because l and w increase by 10% on heating, we have the following: Aheated = (1.10*l)(1.1*w)=1.21(l*w) Because Aoriginal = l*w, Aheated =1.21(l*w)=1.21*Aoriginal So the area of the rectangle increases by 21% upon heating.
P=(L+W)x2 Where P = Perimeter, L=Length and W=Width.
