Work Step by Step

Use the formula for the area of a kite 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 $\frac{x}{y}$, a diagonal, so be sure to double it. 3+3=6 5+5=10 A=$\frac{1}{2}$$d_{1}$$d_{2}$ A=$\frac{1}{2}$(6)(10) A=30
