Question

Match the shapes to their areas with using grids if each square occupies an area of 1 sq cm.

• A. 3 sq cm
• B. 2 sq cm
• C. 6 sq cm

Answer 1

The correct option is

There are 6 full squares in the above grid paper.
$\therefore \text{Area}=6\times 1\text{sq cm}$
$=6\text{sq cm}$


There are 4 half squares in the above grid paper.
$\therefore \text{Area}=4\times \frac{1}{2}\text{sq cm}$
$=2\text{sq cm}$


There are 2 full squares and 2 half squares in the above grid paper.
$\text{Area}=(2\times 1\text{sq cm})+(2\times \frac{1}{2}\text{sq cm})$
$=2\text{sq cm}+1\text{sq cm}$
$=3\text{sq cm}$
