You know that area of a rectangle is A=lw. If you know the area to be 15.86 square inches and the length to be 2.6 inches, you would set up the equation as follows and solve:
A=lw
15.86=(2.6)(w)
You would divide by 2.6 to get w by itself.
You're length would be 6.1 inches.
For you to check for future reference, multiply 2.6(6.1) and you would get 15.86 square inches, which would be your area you started with.

wouldn't your width be 6.1 inches?
