so

Answer 16

If we add 2x to the length and also add 2x to the width we get:
Total length = (4 + 2x) feet
Total width = (3 + 2x) feet
Assume the total area must equal 15 square feet. Then we can write:
(4 + 2x)(3 + 2x) = 15 ...........(1)
Now you need to multiply the two bracketed expressions on the left side of equation (1).
