Answer: approximately 49
Step-by-step explanation:

As we have to solve for b, it means we have to isolate b
So first of all subtract
from both sides
So we get

Now we need b , but its b^2 , so we can take square root on both sides.
taking square roots on both sides

Hence option B is correct
Answer:
Step-by-step explanation:
Perimeter of a rectangle=(length+width)×2
Let W=x, L=2x+2
25=[(2x+2)+x]×2
25=[2x+2+x]×2
Solve for x
25/2=3x+2
25/2-2=3x
25-4/2=3x
21\2=3x=7/2=x
