Answer:
cot(x)
Step-by-step explanation:
Recall the Pythagorean Identity 
A = bh = 11 x 8 = 88

The first thing we must do for this case is to look for the area of each rectangle.
We have then:
A1 = (40) * (x)
A2 = (1.25 * 40) * (y)
Then, we have the following relationship between areas:
"the area of Q is 10% less than the area of p"
A2 = 0.9 * A1
Substituting values we have:
(1.25 * 40) * (y) = 0.9 * ((40) * (x))
We rewrite:
50y = 36x
The relationship x: y is:
x / y = (50) / (36)
Simplifying:
x / y = (25) / (18)
Answer:
the ratio of x:y is:
25:18
This isn't enough information to answer the question. We need to know if he mowed the same lawn 5 times, 5 different lawns, and so on.
If he mowed one lawn 5 times, that would be $150 but if he mowed lawns for different people then the answer is None of the choices are correct because you can eliminate the first two choices for being too low for any possible scenario.
