square sheet of paper has a perimeter of 40 cm what is the length of its side? also find the area of the square feet?

Dear Student,

Given:
Perimeter = 40 cm
‚ÄčAnd we know, Perimeter of a square sheet = 4 x side
=> 40 = 4x side
=> side = 404
=> side = 10 cm

And 
we know area of a square sheet = (side)2
                                                  = (10)2 
                                                  = 100 cm2

Regards
