Given LC = 7.8 cm and UK = 6 cm
Steps :
(i) Drawn a line segment LC = 7.8 cm.
(ii) Drawn the perpendicular bisector XY to LC. Let it cut LC at ‘O’
(iii) With O as centres, drawn arc of radius 3 cm on either side of O which cut OX at K and OY at U.
(iv) Joined LU, UC, CK and LK.
(v) LUCK is the required rhombus.
Calculation of Area :
Area of the rhombus = 12 × d1 × d2 sq.units
= 12 × 7.8 × 6 cm2
= 23.4 cm2
