Exercise 10.2

(a-g)

(a) Number of full squares =

Area of 1 square = 1 sq unit

Area of figure = 9 × 1 sq unit = sq units.

(b) Number of full squares =

Area of figure = 5 × 1 sq unit = sq units.

(c) Number of full squares =

Number of half squares =

Area of the covered figure = 2 × 1 + 4 × 12 = + = sq units

(d) Number of full squares =

Area of the covered portion of the figure = 8 × 1 sq unit = sq units.

(e) Number of full squares =

Area covered by the figure = 10 × 1 sq unit = sq units.

(f) Number of full squares =

Number of half squares =

Area of the covered figure = 2 × 1 + 4 × 12 = + sq units = sq units.

(g) Number of full squares =

Number of half squares =

Area of the covered figure = 4 × 1 + 4 × 12 = + sq units = sq units.

(h-n)

(h) Number of full squares =
