Suppose the length of the base b of a rectangle is increased by 20 percent and the length of the altitude h is increased by 40 p
ercent.
(a) Write an expression, in terms of b, that represents the length of the base of the rectangle after the 20% increase.
(b) Write an expression, in terms of h, that represents the length of the altitude of the rectangle after the 40% increase.
(c) Write an expression, in terms of b and h, that represents the area of the rectangle after both the lengths of the base and altitude are increased.
(d) Increasing a rectangle's base by 20% and altitude by 40% will increase the area by what percentage?
