It's impossible for 2 factors of 12 to add up to 16. So there would be no answer to that.
change yrds to ft
5yds = 5*3 = 15 ft
5yds 2 ft = 15ft + 2ft = 17 ft
6yds = 6 * 3 = 18 ft
6 yds 1 ft = 18 + 1
19 ft
A = l * w
A = 17* 19
A = 323 ft^2
Choice A
Here, Ratio of corresponding length would be equal.
Let, Altitude = x
Then, 64 / x = x / 4
x² = 256
x = √256
x = 16
In short, Your Answer would be 16 units
Hope this helps!
10:24 because if you add up the amount of the books no matter what the genre is you get 24.There are 10 mystery books and it asks for the ratio of mystery books to the total of books so it would be 10:24
