Example Question #291 : Isee Upper Level (Grades 9 12) Mathematics Achievement
Find the area of a rhombus with one diagonal having a length of 12in and the other having a length two times the first diagonal.
To find the area of a rhombus, we will use the following formula:
where p and q are the lengths of the diagonals of the rhombus.
Now, we know one diagonal has a length of 12in. We also know the other diagonal is two times the first diagonal. Therefore, the second diagonal is 24in.
Knowing this, we can substitute into the formula. We get
