## Geometry: Common Core (15th Edition)

288 $in^{2}$
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
