NCERT Solutions for Chapter: Fields and Fences, Exercise 2: Practice Time

Chandu’s father is called the ‘young old man’ in his village. At $70$ years of age, he is fully fit. Do you know his secret? He goes for a walk around the field every morning. Everyday he takes four rounds of Chandu’s field.

What is the total distance he covers? $4\times \_\_\_\_\_=\_\_\_\_\_\mathrm{m}=\_\_\_\_\_\mathrm{k}\mathrm{m}$

Ganpat’s wife works in a tailor’s shop. She has to fix lace around a table cloth. She bought a $100 \mathrm{m}\mathrm{e}\mathrm{t}\mathrm{r}\mathrm{e}$ roll of lace.

How much lace will be left in the roll after using the lace for $3$ such table cloths?

If the required answer is of the form $K \mathrm{m}$, what is the value of $K$?

A square has a boundary of $12 \mathrm{cm}$.

If you cut a $1 \mathrm{cm}$ square to get shape C, what will be the length of the boundary of C?

If the length of the square D is $k \mathrm{cm}$, then write the value of $k$ in the answer box.

$8$ squares of side $1 \mathrm{c}\mathrm{m}$ are cut out of the square $\mathrm{D}$ . Now it looks like shape $\mathrm{E}$. If the length of the boundary of shape $\mathrm{E}$ is $k$ $\mathrm{cm}$, find the value of $k$?

The boundary of this is _____ + _____ + _____ + _____ . Can we also say that the boundary is $4\times 1 \mathrm{c}\mathrm{m}$?

A hockey field is $91 \mathrm{m} 40 \mathrm{cm}$ long and $55 \mathrm{m}$ wide. How long is the boundary of the field? If the required answer is of the form $\left(A\right) \mathrm{m} \left(B\mathit{\right)}\mathit{ }\mathrm{cm}$, what is the value of $B$?

Have you seen any race where runners start from different places like in this picture? Guess why?
