If you would like to know the length of each side of the patio, you can calculate this using the following steps:
an area ... 200 square feet
a ... the length of one side
area = a * a = a^2
200 = a^2
a = sqrt(200)
a = 14.14 feet
The correct result would be 14.14 feet.
Answer:
x = 10
Step-by-step explanation:
To find x, write a proportion between the side lengths for the similar triangles in the figure.

To solve, cross multiply and isolate x.
(x+5)(12) = 18(x)
12x + 60 = 18x
60 = 6x
10 = x
