Question

The area of a rhombus whose diagonals are of lengths 10 cm and 8.2 cm is ____

Answer 1

area= 41 cm^2

Explanation:

area=5 x 8.2 = 41 cm^2

divide the rhombus in half either way and you have two identical triangles.

area of triangle =0.5 x base x height

double that for the two triangles and you have the area of the rhombus.
