Playground

On the special playground, there are 81 square sectors, each with a side of 5 m. How many players can fit on the playground if each player needs a 75 m2 area to play?

Result

n =  27

Solution:

k=81 a=5 m  S=k a2=81 52=2025 m2 S1=75 m2  n=S/S1=2025/75=27k=81 \ \\ a=5 \ \text{m} \ \\ \ \\ S=k \cdot \ a^2=81 \cdot \ 5^2=2025 \ \text{m}^2 \ \\ S_{1}=75 \ \text{m}^2 \ \\ \ \\ n=S/S_{1}=2025/75=27



Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
