Question

estimate the area of these irregular shapes by counting the squares. assume that each side of the unit square is 1 cm.
full squares - 14
half squares - 1
more-than-half squares - 2
area ∼ ___ sq. cm

Answer 1

So, the area = (9x1)(6x1)=15cm

so it is greater than the rectangle by =15−12=3 sq. cms
