NCERT Solutions for Chapter: How Many Squares?, Exercise 5: Puzzles with Five Squares

How many different shapes can you draw using $5$ squares$?$

Figure (d) has the smallest perimeter, find the perimeter of the remaining figures in $\mathrm{cm}$ where perimeter of remaining figures are same(Consider side of a small square has $1 \mathrm{cm}$).

Each side of the smallest square in the given diagram is of $1 \mathrm{cm}$. If the perimeter of the shape $\left(\mathrm{d}\right)$ is $k \mathrm{cm}$, write the value of $k$.

Each square area in the given diagram is of $1 \mathrm{square} \mathrm{cm}$. If the area of the each shape is $k \mathrm{square} \mathrm{cm}$, find the value of $k$.
