Question

Find the diagonal of a rhombus of side 6cm whoes one of the diagonal is 8 cm long & altitude is 4.2 cm..

Answer 1

Step-by-step explanation:

Rhombus is a parallelogram.

So, it's area= b*H

Base = 6cm

Height = 4.2 cm

Area = 6cm * 4.2cm

=25.2cm sq.

Area of rhombus= 1/2* dig.1 * dig.2

Area= 1/2 * 8cm * dig.2 = 25.2cm sq.

dig.2 = 25.2cm sq./4cm

dig.2 = 6.3cm
