I think the answer would be 21 zombies left. I used subtraction to figure this out.
The area of pasture is 60000 square feet.
Step-by-step explanation:
Perimeter of rectangular pasture = 1000 feet
Width of pasture = w
Length of pasture = l = w+100
We know that,
Perimeter = 2(Length+width)
Dividing both sides by 4
Width is 200 feet.
Length = w+100 = 200+100 = 300 feet
Area of pasture = A = Length * Width
The area of pasture is 60000 square feet.

Answer: 13.
Look at the height and the x. The measurements look very similar, and since the height= 12, 13 is the closest answer to 12 out of the three given answers, so 13 is the value of x.
