Answer 1

Step-by-step explanation:

We have

length =200M

breadth =150M

Now,

Total length have to run by an athelete = perimeter of rectangular playground

=2(length+breadth)

=2(200+150)M

=700M

Hence, the total distance run by an athelete is 700M.

Answer 2

$\Large{\underbrace{\sf{\purple{Required\:Answer:}}}}$

⛦Given :

• The length of a playground =200 m
• The breadth of a playground= 150m
• an athlete wants to run 7 km,this playground

⛦To Find :

• Perimeter=?
• Round taken by an athlete=?

⛦Knowledge Required :

We know thαt,

$\large\star{\boxed{\sf{\orange{Perimeter_{(rectangle)} = 2(length+breadth)}}}}$

⛦Solution :

Perimeter = 2(l+b)

=2(200+150)

=2•350

= 700

⟼an athlete wants to run 7 km

⟼To run 7 km or 7000 m he needs to go around = 7000 \ 700

$\large\longrightarrow{\boxed{\sf{\red{ 10 rounds}}}}$

Hence, the Round taken by an athlete= 10....
