Practice makes perfect

We are told that are of a kite is 50 inches. We are also told that the area is 150in.^2. Let's draw a diagram to illustrate the situation.

The area of a kite is half the product of its diagonals. A=1/2d_1 d_2 We can substitute A= 150, d_1= 50, and d_2= d into this formula and solve for d, one of the diagonals. Let's do it!
A=1/2d_1 d_2
150=1/2 50 d
150=25d
6=d
d=6
