The area of a rhombus is `240\ c m^2` and one of the diagonal is 16cm. Find another diagonal.

Explanation

The area of the given rhombus is `240cm`. A rhombus has two diagonal, which connect the opposite vertices, and the parallel sides. Thus using congruent triangles it can be said that a rhombus is symmetry along the diagonals.
Therefore, the “area of the rhombus” is equal to `1/2 xx D xx d`.
Now the “area of the rhombus” is given as which if equated gives `240=1/2 xx 16 xx D`
`D=30cm`
Therefore, one of the diagonals of the rhombus of area `240`, is `16` and the other one is `30cm`.
