Answer 1

Answer:

Step-by-step explanation:

Question-:

An athlete takes 5 rounds of a rectangular park, 80 m long and 30 m wide. Find the total distance covered by him.​

Solution-:

Perimeter of rectangular park=2*(l+b)

Perimeter of rectangular park=2*(80+30)m

Perimeter of rectangular park=2*110

Perimeter of rectangular park=220m

Since athlete takes 5 round of rectangular park so= 5*220

So he covers 1100m in 5 rounds

We can also covert m to km so=1100m=1.1km

therefore he covers 1.1km in 5 rounds

Answer 2

• The total distance covered in 5 rounds is 1100 m or 1.1 km.

Given :-

• Length of the park = 80 m.
• Breadth of the park = 30 m.
• The athlete takes 5 rounds around the park.

To find :-

• The total distance covered by him.

Step-by-step explanation :-

The park is in the shape of a rectangle, who's length is 80 m and width is 30 m.

To find the answer, first we have to find the perimeter of this rectangular park.

For that, we will apply this formula :-

Perimeter of a rectangle = 2 (Length + Breadth)

Substituting the values, we get :-

$\bf Perimeter = 2 (80 \:m + 30 \:m)$

$\bf Perimeter = 160 \: m + 60 \: m$

$\bf Perimeter = 220\:m.$

The perimeter of the rectangular park is 220 m.

The distance covered by the athlete in 1 round = 220 m.

He takes 5 rounds around the park.

Therefore, total distance covered by him = 220 m × 5 = 1100 m.

Thus, the total distance covered by the athlete is 1100 m or 1.1 km.
