Answer
Explanation:
Step1: Calculate area of Corral 1
Area of rectangle = length×width, so area of Corral 1 is $50\times40 = 2000$ square - meters. Area per - animal is $\frac{2000}{110}\approx18.18$ square meters.
Step2: Calculate area of Corral 2
Area of Corral 2 is $60\times35 = 2100$ square - meters. Area per - animal is $\frac{2100}{115}\approx18.26$ square meters.
Step3: Calculate area of Corral 3
Area of Corral 3 is $55\times45 = 2475$ square - meters. Area per - animal is $\frac{2475}{125}=19.8$ square meters.
Step4: Calculate area of Corral 4
Area of Corral 4 is $65\times40 = 2600$ square - meters. Area per - animal is $\frac{2600}{130}=20$ square meters.
Answer:
D. Corral 4
