<u>Answer:</u>
8 meters or 4 meters
<u>Step-by-step explanation:</u>
We know that for finding the area of a rhombus, there are two diagonal sides: one of which is 12.5 meters in length and the other one we'll assume to be y.
Then, we can write:
Area of rhombus =


meters
If the sides of the rhombus are not internally diagonal, then we can simply use the following formula:
Area of rhombus = altitude * side

meters
