Question

If the area of a rhombus is 100 square inches and one of the diagonals is 25 inches long, what is the length of the other diagonal?

Answer 1

8 inches.

Explanation:

Area of rhombus =
`(pq)/(2)`

Where p is 25 ( one of the lengths) and the q is the other one.

Substituting we should have something like this:
`(25 q)/(2) = 100`

Solving for q, we get q = 8.

Hope this helps.
