The area of the rect. is 100 ft times 64 ft, or 6400 ft^2.
Let's list factors of 6400: 64,100
64= 2^6
100= 2^2*5^2
Here we see that 2 appears 8 times as a factor, and 5 appears 2 times:
6400 = 2^6 * 10^2 = 2^8*5^2
A nine can go into a 20 two whole times. After that, there's still
some room left in the 20, but it's only enough room for a 2.
28 minutes
45 - 11 divided by 2 = 17 + 11 = 28 minutesa
The answer is 1.715 hope I helped
