The playground

The playground has the shape of a square with a side of 64 m. It is fenced on three sides. What is the area of the playground and how long is its fence?

Result

S =  4096 m2
o =  192 m

Solution:

a=64 m  S=a a=64 64=4096 m2a=64 \ \text{m} \ \\ \ \\ S=a \cdot \ a=64 \cdot \ 64=4096 \ \text{m}^2
o=3 a=3 64=192 mo=3 \cdot \ a=3 \cdot \ 64=192 \ \text{m}



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!
