Question

Find the area of the shape shown in the figure:

[2 marks]

Answer 1

According to the given figure,
Number of Fully-filled squares = 3
Number of Half-filled squares = 3

[0.5 mark]

∴ Area covered by full squares = 3 × 1 = 3 sq units
and Area covered by half-filled squares = 3 × $\frac{1}{2}$
= $\frac{3}{2}$ sq units

[0.5 mark]

Hence, the total area of the shape = Area covered by full squares + Area covered by half-filled squares $=3sqcm+\frac{3}{2}sqcm=4\frac{1}{2}squnits.$
