Answer 1

Question ::-

The length of a rectangular play ground is 75m and it's breadth is 50m Rupali walk four rounds. How many kilometres did she walk?

Given ::-

• Length of rectangle = 75 m

• Breadth of rectangle = 50 m

To find ::-

• Find the perimeter of rectangle ?

Solution ::-

Rupali walks around rectangular park , i.e. It's perimeter. She take four rounds.

Perimeter = 2 (length + breadth )

Perimeter = 2 ( 75 + 50 )

Perimeter = 2 × 125

Perimeter = 250

_______________

Total distance Rupali cover = 4 × 250

= 1000 m = 1Km

Answer 2

Question :-

• The length of a rectangular play groundis 75m and it's breadth is 50m. Rupali walk four rounds. How many kilometres did she walk ?

ㅤ‎‎‎‎ㅤㅤㅤㅤㅤ

ㅤ

✠ Given :-

• Length of ground = 75 m
• Breadth of ground = 50 m
• Rupali walks four rounds.

ㅤ

✠ To find :-

• Distance she walked in km's.

ㅤ

ㅤ

✠ Formula to remember :-

• Perimeter of rectangle = 2 × ( l + b)

ㅤ‎‎‎‎ㅤㅤㅤㅤㅤ

✠ Solution :-

ㅤ‎‎‎‎➨ Distance she walked in one round :-

╺ Perimeter = 2 ( 75 + 50)

ㅤ‎‎‎‎ㅤㅤㅤㅤ= 2 ( 125 )

ㅤ‎‎‎‎ㅤㅤㅤㅤ= 250 m

➨ Distance she will cover in 4 rounds :-

➯ Distance in 1 round × 4

ㅤ‎‎‎‎ㅤㅤㅤㅤㅤ = 250 × 4

ㅤ‎‎‎‎ㅤㅤㅤㅤㅤㅤ‎‎‎‎ㅤㅤㅤㅤ

ㅤ‎‎‎‎ㅤㅤㅤㅤㅤ= 1000 m

↝ Therefore , she will cover 1000m in 4 rounds.

☞ Now, Converting metres into km's :-

Divide it by 1000 :-

ㅤ‎‎‎‎ㅤㅤㅤㅤㅤ= 1000/1000

ㅤ‎‎‎‎ㅤㅤㅤㅤㅤ= 1 km

↝ Therefore, she will cover 1 km.
