Is every relation also a function? explain

"All functions are relations but all relations are not functions."

Functions are the relation that classifies the set of outputs to the set of inputs. Moreover relation is identified as the group of ordered pairs.

A relation is a way of expressing a connection or relationship between any two pieces of information.

Thus, every relation is not a function.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
