Inequalities help us to compare two unequal expressions. Corral number 4 meets this requirement.
<h3>What are inequalities?</h3>
Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.
Let the length of the corral be represented by L, and the width of the corral be represented by W, while the number of animals be represented by N.
To find if a corral meets the requirement find the product of the length and the width of the corral, and then divide it by the number of animals. The inequality that can represent this situation can be written as,
20≥[(L×W)/N]
For Corral1,
[(50×40)]/110
=18.18
Since the inequality is not satisfied it is not the required corral.
For Corral2,
[(60×35)]/115
= 18.26
Since the inequality is not satisfied it is not the required corral.
For Corral3
[(55×45)]/125
=19.8
Since the inequality is not satisfied it is not the required corral.
For Corral4,
[(65×40)]/130
=20
Since the inequality is satisfied it is the required corral.
Hence, corral number 4 meets this requirement.
