Given:
height of parallelogram increased by 1cm
base of parallelogram increased by 2cm
To find:
New area of paralellogram
Solution:
Area of a parallelogram is equal to the product of base and height.
area of parallelogram = Bh
where B is base and h is height.
If base is increased by 1cm
new base = B + 1 cm
if height of parallelogram is increased by 2 cm
new height = h +2cm
new area of parallelogram = (B+1)(h +2)
= Bh + 2B + h +2 square centimetre.
Area of new parallelogram is Bh + 2B + h + 2 square centimetre.
