Question

A rectangular garden is 120m by 100m how many round of the garden will a girl make if she covers 2200 meters​

Answer 1

$\huge\mathcal{\fcolorbox{aqua}{azure} {\red{Answer}}}$

Given :-

• Length = 120 m

• Breadth = 100 m

• He covered = 2200 m

calculate the Perimeter.

We know that,

${Perimeter\:of\:a\:Rectangle\:=\:2[Length\:+\:Breadth]}$

Substituting values in Formula,

We Get,

${Perimeter\:=\:2[120\:+\:100]}</p><p>$

${Perimeter\:=\:2[220]}$

$\sf{Perimeter\:=\:440\:m}$

It is given that, He covers a total distance of 2200 meter, and As we know the Perimeter is = 440 m. We could understand that in one round he could complete 440 m.

So, No. of. Rounds the boy would cover,

${No.\:of.\:Rounds\:={\dfrac{Total\:Distance\:Covered}{Perimeter}}}$

$\sf{No.\:of.\:Rounds\:=\:{\dfrac{2200}{440}}}$

$\sf{No.\:of.\:Rounds\:=\:5}$

Hence, he could complete 5 rounds covering 2200 m.

Answer 2

Answer:

Number of rounds the girl makes= 5

Step-by-step explanation:

Given:

Length= 120m and Breadth= 100m

So, Perimeter of the garden= 2(Length + Breadth)

or 2×(120+100)

or 2×220

or Perimeter of the garden= 440m

So, as the girl covers 2200m

So, the number of rounds she makes=

Distance she covers/Perimeter of the garden

or 2200/440= 5

or Number of rounds the girl makes= 5

Hope this helps...
