Question

Find the perimeter of the shape on this centimeter grid.

Answer 1

Here, We will determine the sides first of all

We are assuming that 1 block measures 1cm. So, According to this assumption the number of blocks the side covers is equal to the length of that side (in cm)

$\rule{300pt}{3pt}$

The sides are; 2cm, 4cm, 2cm, 4cm, 7cm, 3cm

Now,

$\sf \longmapsto perimeter = Sum \: of \: all \: sides$

Putting values of sides;

$\sf \longmapsto 2 + 4 + 2 + 4 + 7 + 3$

$\sf \longmapsto Perimeter=22cm$
