Step-by-step explanation:
so, I assume the patio is a true rectangle.
the area of a rectangle is
length × width
in our case that means
1.3 = 5 × width
width = 1.3 / 5 = 0.26 ft
so, this is just a very narrow strip of 0.26ft × 5 ft.
I would not call that a patio ...
or was it a typo, and the area is actually 30 ft² ?
then we would have
30 = 5 × width
width = 30 / 5 = 6 ft
