Aisha wants to make two quilts, each with the same area. The first quilt will be square with sides s feet long. The second quilt
Illusion [34]

Answer:

None of the option is true

Step-by-step explanation:

As per the given condition , the length of rectangle = s+6 and width = \frac{s}{2}

Hence the Area will be A=\frac{s}{2}*(s+6)

This area is the same as that of Square, whose area was s^{2}

Hence the Area will be

s^2=\frac{s}{2}*(s+6)

2s^2=s(s+6)\\2s^2=s^2+6s\\s^2-6s=0\\s(s-6)=0\\

s=0 , s=6
