+359 If the area of a rhombus is 20 square inches and one of its diagonals is 10 inches, what is the length, in inches, of the other diagonal?
+34 The formula for the area of a rhombus is \(A=\frac{pq}{2}\) A representing the area, and p and q as the two diagonal lengths
You can plug in the area and one of the diagonals to get \(20=\frac{10q}{2}\)
Now you just solve for q. 40 = 10q, q=4
The length of the other diagonal is 4
