Question

Find the perimeter of the closed figure given below.

Answer 1

Perimeter: Perimeter of a shape is calculated by adding all the distance or length around the shape.

Calculation: In the given figure there are total $5$ sides that are $\mathrm{PT},\mathrm{TS},\mathrm{SR},\mathrm{RQ},\mathrm{QP}$

Thus, the perimeter of the given figure will be sum of lengths of all the sides

Perimeter$$\begin{gathered} =2.4+1.3+1.4+2.6+4.2 \\ =11.9 \end{gathered}$$

Hence, perimeter$=11.9cm$
