Question

Find the area of the shape shown in the figure:

Answer 1

This figure is made up of line segments moreover, it is covered by full squares and half squares only. This makes our job simple.
We have,
Fully filled squares =3
Half-filled squares =3
Area covered by full squares $=3\times 1sq.units=3sq.units$
Area covered by half squares = $3\times \frac{1}{2}sq.units=1\frac{1}{2}sq.units$
Total area $=3+1\frac{1}{2}=4\frac{1}{2}squnits.$
