Example 1: Find the area of figures drawn on the squared paper.

(a)

(b)

(c)

(d)

Solution: (a) Number of complete squares = 12

∴ Area of this figure = 12 sq. units

(b) Number of complete squares = 4

∴ Area of this figure = 4 sq. units
(c) Number of complete squares = 6

Number of half squares = 2, i.e., 1 complete square
∴ Area of the figure = 6 + 1 = 7 sq. units

(d) Number of complete squares = 6

Number of more than half squares = 2

Number of half squares = 2, i.e., 1 complete square

∴ Area of the figure = 6 + 2 + 1 = 9 sq. units

Finding Areas Using Formulas

Consider the rectangle 1 (a) again. Length of the rectangle = 4 squares

and breadth = 3 squares

Area calculated in 1 (a) = 12 sq. units

= 4 × 3 sq. units

= Length × Breadth
