Answer:

Side = 5\sqrt{2 } cm

Perimeter = 20\sqrt{2} cm

Step-by-step explanation:

We know, Diaganol of square = a\sqrt{2}

Given,                        Diaganol = 10cm

                                          a\sqrt{2} = 10

                                               a = \frac{10}{\sqrt{2} }

                                               a = \frac{10}{\sqrt{2} } . \frac{\sqrt{2} }{\sqrt{2} }

                                               a = 5\sqrt{2} cm

                                 Perimeter = 4a

                                                  = 4 x 5\sqrt{2}

                                                  = 20\sqrt{2} cm
