Answer 2

The area of the rectangular ground in 0.72 hectares

Step-by-step explanation:

• Given data

        Side of square (a) = 90 m

        Perimeter of square (P) = 4×Side

        Perimeter of square (P) = 4×90 = 360 m

• Given that

        Width of rectangle (B)= X

        Length of rectangle (L)= 2X

• We know that

        Perimeter of rectangle = 2(L+B)

• Again it is given that perimeter of rectangle is equal to the perimeter of square. Means

        Perimeter of rectangle = Perimeter of square

• 2(L+B) = 360

        2(2X +X) =360

        2×3X =360

        6X =360

        X = 60

• So

        Width of rectangle (B)= X = 60 m

        Length of rectangle (L)= 2X = 2× 60 = 120 m

• We know the area of rectangle that

       Area of rectangle = Length× Width

        Area of rectangle = 120× 60= 7200 m² = 0.72 Hectares
