Question

By counting squares, estimate the area of the figure.

Answer 1

Covered area	Number	Area estimate (sq units)
(i) Fully-filled squares	11	11
(ii) Half-filled squares	3	`3 xx 1/2`
(iii) More than half-filled squares	7	7
(iv) Less than half-filled squares	5	0

Total area = 11 + 3 × `1/2 + 7 = 19 1/2` sq units.
