Step-by-step explanation
you take a your square which has 4 sides to it, the take the number of the potential answers, divide each answer by 4. which ever answer comes out even and but also the smallest while being even is your answer. Makes sense?
1) 950/4=237.5, this is not even/a perfect square
2)1200/4=300, this comes to have 4 even sides of 300 making it a perfect square and being the smallest value
3)1500/4=375, also a perfect square but not the smallest value
4)1750/4=437.5, not a even number
5)10700/4, perfect square but no the smallest value
i believe this is correct

<span>width = x
</span><span>length = x+5
2x + 2(x+5) = 46
2x + 2x + 10 = 46
4x = 46 - 10
4x = 36
x = 36/4 </span><span>
x = 9 in </span> ← width
length = x+5 = 9 + 5 = 14 in
<span>
Area = 9 * 14 = 126 in</span>²<span>
