Answer 1

Answer:

line segment joining the mid point of any side with the opposite vertex is called iska answer batao

Answer 2

Answer :-

• Jogging three times around the park, we won't be able to cover 1 km.

• Distance covered on jogging three times = 750 m.

Given :-

• A park is 75 m long and 50 m wide.

To find :-

• If we will cover at least 1 km after jogging three times around it.

Step-by-step explanation :-

• In this question, the length and breadth of the park has been given to us, that means it's a rectangular park. Since we have to find the distance covered after jogging three times around it, therefore we have to find the perimeter and not the area, because we have to find the boundaries.

-----------------------------------------------------------

Calculations :-

Let's use the formula required for finding the perimeter of a rectangle to find the perimeter of the park.

We know that :-

$\underline{\fbox{\sf Perimeter of a rectangle = 2 (L + B).}}$

Here,

• Length = 75 m.
• Breadth = 50 m.

Therefore,

$\tt Perimeter = 2 \: (75 \: m + 50 \: m)$

$\tt Perimeter = 2 \: (125 \: m)$

$\overline{\fbox{\tt Perimeter = 250 \: m.}}$

• The perimeter of the park is 250 m, which means that on jogging around it for one time, we can cover 250 m.

Hence, on jogging around the park for three times, the distance covered = 250 m × 3 = 750 m.

$\fbox{\bf Distance in 3 rounds = 750 m.}$

First let's make the units same.

We know that :-

$\fbox{\bf1 km = 1000 m.}$

Now let's compare 750 m and 1000 m.

It's clear that :-

$\fbox{ \bf750 m is smaller than 1000 m}$

Thus, on jogging around the park for three times, we won't be able to cover 1 km.
