Answer 2

Answer:

As the diagonals of rhombus are perpendicular bisector of each other. As, any diagonal cuts the rhombus into two concurrent triangles.

So, area of one triangle = 12bh

Here one of the diagonal is base and half of the other diagonal is height of one of the triangle.

Let b = 10 cm, so h = 12×8 cm

So, area of triangle = 12×10×4

=20cm2

Area of rhombus = 2 × (area of triangle)

=2×20cm2

=40cm2
