Answer
288 $in^{2}$
Work Step by Step
Use the formula for the area of a rhombus which is A=$\frac{1}{2}$$d_{1}$$d_{2}$.
Remember "d" represents the length of the diagonals.
In the diagram you are only given the measurement of half a diagonal, so be sure to double it.
12+12=24
12+12=24
A=$\frac{1}{2}$$d_{1}$$d_{2}$
A=$\frac{1}{2}$(24)(24)
A=288
