Thank you for the opportunity to help you with your question!

area of square pendant = 10 cm sq

formula for area of square = side * side

10 = side * side   

this can be written as

10 = (side)^2

now square root both sides

sqrt 10 = side

side = 3.17 cm

Please let me know if you need any clarification. I'm always happy to answer your questions.

10 = (side)^2

in order to remove square of side, we square root both sides
