Question
Find the area of the rhombus, if its diagonals are 30 cm and 24 cm.
Solution
Given, diagonal (d1) = 30 cm
Other diagonal (d2) = 24 cm
If AC and BD are the diagonals of a rhombus its
Area =`1/2xx"Product of it diagonals"`
= `1/2xx"AC"xx"BD"`
= `1/2xx"d"_1xx"d"_2`
= `1/2xx30xx24 "cm"^2`
= 15 × 24 = 360 cm2
∴ Area of rhombus = 360 cm2
