In rhombus ABCD, AB=18 and AC=26. Find the area of the rhombus to the nearest tenth.

From equation :

$|AB|^2=\left(\frac{|AC|}{2}\right)^2+\left(\frac{| BD|}{2}\right)^2$

you can find value of $|BD|$ an after that calculate area $A$ :

$A=\frac{|AC|\cdot |BD|}{2}$

have you made a sketch?

area, $A = \frac{d_1 \cdot d_2}{2}$

where $d_1$ and $d_2$ are diagonal lengths ... you should also know that the diagonals of a rhombus are perpendicular and bisect each other.

hmmm ... Pythagoras?
