(ii) Can you now think of similar other situations in which
two algebraic expressions have to be multiplied?
Ameena gets up. She says, "We can think of area of
a rectangle." The area of a rectangle is Ix b, where!
is the length, and b is breadth. If the length of the
rectangle is increased by 5 units, i.e., (1 + 5) and
breadth is decreased by 3 units, i.e., (b - 3) units,
the area of the new rectangle will be (1+5) x (b-3).
