Answer 1

AnSwer -:


They have covered 3 rounds by walking

1320

_______________________________

Explanation-;

Perimeter of rectangle-:

“P = 2(l+b)”

P = Perimeter

L = length

B = breadth

______________________________

Given ,

Dimensions of the rectangular garden

120 m by 100 m

A girl walk 1320 m

To find,

Number of rounds they have covered. in

1320 m

______________________________

Perimeter of rectangle-:

“P = 2(l+b)”

P = Perimeter

L = length =120 m

B = breadth = 100 m

Now ,

2 ( 100 + 120)

2 x 220

440 m

Therefore,

Perimeter of rectangular garden.

is 440 m

Now ,


Number of rounds they have covered -:

The total distance they have covered /

perimeter of rectangular garden

They have covered 1320 m

Perimeter of rectangular garden-: 440 m

Now

1320/440

= 3

Hence ,

They have covered 3 rounds by walking

1320 m

Answer 2

Hey,

In ᴛʜɪs ϙᴜᴇsᴛɪᴏɴ ᴡᴇ ғɪɴᴅ ᴛʜᴇ ʀᴏᴜɴᴅs ᴛᴀᴋᴇɴ ʙʏ ɢɪʀʟs....

Given:-

• ᴛʜᴇ ʟᴇɴɢᴛʜ ᴏғ ᴛʜᴇ ɢᴀʀᴅᴇɴ ɪs 120ᴍ
• ᴛʜᴇ ʙʀᴇᴀᴛʜ ᴏғ ᴛʜᴇ ɢᴀʀᴅᴇɴ ɪs 100ᴍ
• ᴀɴᴅ ɢɪʀʟs ᴄᴏᴠᴇʀ 1340 ᴍ

To Find:-

• ᴛʜᴇ ʀᴏᴜɴᴅs ᴛᴀᴋᴇɴ ʙʏ ᴛʜᴇ ɢɪʀʟs....

As We Know:-

• 1st ᴡᴇ ғɪɴᴅ ᴛʜᴇ ᴘᴇʀɪᴍᴇᴛᴇʀ
• ᴘᴇʀɪᴍᴇᴛᴇʀ ᴏғ ʀᴇᴄᴛᴀɴɢʟᴇ 2×(ʟ+ʙ)

Solution:-

ᴘᴇʀɪᴍᴇᴛᴇʀ = 2 × ( ʟ + ʙ )

= 2 × ( 120 + 100 )

= 2 × ( 220 )

= 440 ᴍ

ɴᴏ. ᴏғ ʀᴏᴜɴᴅs = 2200/440

= 5

Therefore,

A girls ᴍᴀᴋᴇ 5 ʀᴏᴜɴᴅs ᴀʀᴏᴜɴᴅ ᴛʜᴇ ʀᴇᴄᴛᴀɴɢᴜʟᴀʀ ɢᴀʀᴅᴇɴ.
