Answer:
the equation equal 22.5ft in length, which is close to user above me
Explanation:
a rectangle that's a total of 48 total
1.5ft wide which is times by 2 which would be 3 ft out of the picture, aka means we will have to subtract that from the total since he know 3ft is already to the widths so 48 - 3 will lead to 45, 45 split into two sides will give you the total of this size of length
divide 2 by 45 will equal 22.5
