We know in finding the Area of rhombus is taking the diagonal sides, so I assumed the one given is a diagonal side=12.5m, mark as "x". And the other diag. side marked as "y"----> unknown?
So,
A=%281%2F2%29xy
50=%281%2F2%29%2812.5%29%28y%29
y=100%2F12.5
y=8m
*Alternate sol'n:
The above solution is applicable if given side is the diagonal side internal. Let say you have a rhombus ABCD, the diagonal sides are AC & BD.
If that's not the case, we apply formula for the rhombus, A=altitude%2Aside
Substituting the given,
50m%5E2=a%2A12.5m
a=50%2F12.5 ----------------> a=4m, altitude
