Answer:
l = 16 feet
Step-by-step explanation:
P = a + b + c + d.
P = 2x + x + 2x + x = 48
6x = 48
x = 48/6
x = 8 feet
Thus, length = 2x = 2(8) = 16 feet
X = the number of humans and y = the number of horses.
x+y=74
2x+4y=196
Because the number of humans and horses together is 74, and the total number of legs (2 per every human, x, and 4 per every horse, y) is 196. Then, just use elimination to solve.

So, now that you have y, you can plug it into the first equation to find x:

So, x = 50 and y = 24, so there are 50 humans and 24 horses.
The correct answer is B.
