#### Answer

30 $ft^{2}$

#### 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
