Answer:
225
Step-by-step explanation:
Some other numbers that would work are:

Similar triangles are proportional, meaning one will be a factor larger or smaller than the other. This factor will be the same for all of the sides. So, we can say that one corresponding pair of sides is equal to another corresponding pair of sides.
BA / ED = AC / CD
42 / 6 = (64 - x) / (x)
6(64 - x) = 42(x)
384 - 6x = 42x
384 = 48x
x = 8

The distance formula is distance(d) = rate(r) x time(t). In this problem we are trying to find the distance and we are given the rate which in this case is 66.8 feet per minute * 2 and the time is 30 minutes. We can substitute this into our equation we get:
D = <span>133.6 x 30. When we multiply this out we get D = 4008 ft.</span>
6.5^2 x 6.5^2= 1785.0625
Answer: 1785.1 sq units
