Solve for b A=\frac{9}{2}\left(b+35\right)
b=\frac{2A}{9}+35
b=\frac{2A-35}{9}
b=\frac{2A}{9}-35
b=\frac{2A+35}{9}

Can the perimeter of the rectangle be 60 units when its width is 11 units and its length is 24 units?
Yes, P = 2L + 2W = 60
Yes, P + W is greater than 48
No, the perimeter would be 70, not 60.
No, the perimeter would be 66, not 60
