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
30 60 90 right triangle on the right
ratio of short leg: long leg :hypo = a: a√3: 2a
So if hypo = 52 cm then short leg = 52/2 = 26 cm
The other right triangle on the left is 45 45 90 because it has 2 equal sides
ratio of leg: leg :hypo = a: a: a√2
the leg = 26 cm
so hypo x = 26√2
Answer
26√2 cm
