The diagonals of a rhombus are 7.5 cm and 12 cm. Find its area
Solution:
Let's construct a rhombus ABCD as shown below
Let CB and AD be the diagonals of the rhombus ABCD.
AD = 7.5 cm, CB = 12 cm
Area of Rhombus ABCD = Area of ΔABC + Area of ΔDCB
= 1/2 × (CB × AO) + 1/2 × (CB × OD)
= 1/2 × CB × (AO + OD)
= 1/2 × CB × AD
= 1/2 × 12 m × 7.5 m
= 45 m²
