Answer:

Area of a square is 441 m^{2}.      

Step-by-step explanation:

Given : Perimeter of a square = 84 m

To find : Area of a square = ?

Solution :

  • It is given that the perimeter of a square = 84 m
  • We have to find the area of a square.
  • We know that, perimeter of a square is the sum of all sides of the square.
  • Square has four sides and the length of each side is equal.
  • The formula for perimeter of a square is given by,

              Perimeter of a square = 4*side

                                           84 = 4*side

                                     ∴ Side = \frac{84}{4}

                                      ∴ Side = 21 m

  • Now, the formula for area of a square is given by,

           Area of a square = side^{2}

                                     = 21^{2}

                                     = 441 m^{2}

  • ∴ Area of a square is 441 m^{2}.
