Answer: 40 cm

Step-by-step explanation:

Area = length x width

A square has 4 equal sides so length = width (they have to be the same number)

10cm x 10cm = 100cm^2 or the square root of 100cm^2 = 10cm

10cm x 4 sides = 40cm

Answer:

A) 40 cm

Step-by-step explanation:

Side of square =√ Area  

                       =  √100 = √10*10

                      = 10 cm

Perimeter of square = 4 *side

                                  = 4 * 10

                                 = 40 cm
