Perimeter of square

The square has a circumference 17cm. What is its area?

Result

S =  18.063 cm2

Solution:

o=17 cm a=o/4=17/4=174=4.25 cm  S=a2=4.252=28916=18.0625=18.063 cm2o=17 \ \text{cm} \ \\ a=o/4=17/4=\dfrac{ 17 }{ 4 }=4.25 \ \text{cm} \ \\ \ \\ S=a^2=4.25^2=\dfrac{ 289 }{ 16 }=18.0625=18.063 \ \text{cm}^2
