The area of a rhombus is 94ft^2, one diagonal is 18ft long. find the length of the other diagonal?

Data:
A (Area) = 94 ft²
D (long diagonal ) = 18 ft
d (lenght diagonal ) = ?

The area of the diamond can be calculated using the following formula.



Solving:

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.
