Question

Find area of a square shaped plot whose perimeter is 84 meter.

Answer 1

Perimeter = 84 m

4×side = 84 cm

side = $\dfrac{84}{4}$ cm

Side = 21 cm

Now ,

Area = Side²

Area = (21cm)²

Area = 441 cm²

Answer 2

Answer:

Perimeter of Square shaped plot = 84 meter

then side of Square = Perimeter of square/all side of square

                                   = 84/4    

                                    = 12 meter

Now, Area of Square = side X side

                                    = 12 X12

                                    = 144 sq.meter
