Question

Find the perimeter of a square whose side measure: a) 4.5 cm, b) 5.8 m,
c) 27 mm, d) 9 cm, e) 2.2 cm

Answer 1

Answer:

a)18 cm    b)23.2 cm    c)108mm     d)36cm     e)8.8cm

Step-by-step explanation:

Since all sides are equal in a square

perimeter of a square = 4×side

a)Side of a square = 4.5cm

  perimeter of a square = 4×side

                                       = 4×4.5

                                        =18cm

b)Side of a square = 5.8cm

perimeter of a square = 4×side

                                     =4×5.8

                                      =23.2cm

c)Side of a square = 27mm    

perimeter of a square = 4×side                                              

                                     =4×27

                                     =108mm

d)Side of a square = 9cm

perimeter of a square = 4×side

                                     =4×9

                                      =36cm

e)Side of a square=2.2cm

  perimeter of a square = 4×side

                                        =4×2.2cm

                                        =8.8cm
