Question

the area of rhombus and that of square are equal the side of square is 6 cm. if one of the diagonal of the rhombus is 4 cm then find the length of its other diagonal

Answer 1

Side of Square = 6 cm

Area of Square = a^2 = 36

Area of Square = Area of Rhombus = 36 cm^2

One Diagonal of rhombus = 4 cm

Other Diagonal of rhombus = x cm

Area of Rhombus = Product of Diagonals / 2

                36    =    4x / 2

            x = 18

Other Diagonal of rhombus = 18 cm
