Question

3. The length and breadth of
rectangular field is 115 metres and
76 metres respectively. What
distance will a boy cover in walking
around the play ground three
times?​

Answer 1

Answer:

• A boy will cover 1146 metres in walking around the play ground three times.

Step-by-step explanation:

Given that:

• The length and breadth of rectangular field is 115 metres and 76 metres respectively.

To Find:

• What distance will a boy cover in walking around the play ground three times?

Formula used:

• Perimeter of a rectangle = 2(Length + Breadth)

Finding the length of one round of rectangular field:

⇒ Perimeter = 2(115 + 76)

⇒ Perimeter = 2(191)

⇒ Perimeter = 382

∴ The length of one round of rectangular field = 382 metres

Finding the length of three rounds of rectangular field:

∵ The length of one round of rectangular field = 382 metres

∴ The length of three rounds of rectangular field = (382 × 3) metres

∴ The length of three rounds of rectangular field = 1146 metres

Answer 2

Question:-

• The length and breadth of rectangular field is 115 metres and 76 metres respectively. What distance will a boy cover in walking around the play ground three times?

To Find:-

• Find the distance will a boy cover in walking around the play ground three times?

Solution:-

Here ,

We have to find length of one round of rectangular field:-

$\tt\implies \: Perimeter = 2( 115 + 76 )$

$\tt\implies \: Perimeter = 2( 191 )$

$\tt\implies \: Perimeter = 382$

Hence ,

• Perimeter of rectangular field is 382.

Now ,

We have to find the length of three rounds:-

• $\tt\implies \: 382 \times 3$

• $\tt\implies \: 1146 \: meter$
