* W = 300 sq ft

Length is 10 ft greater than twice the width.
L = 2W + 10
Substituting
(2W+10)*W = 300
2W^2 + 10W = 300
Divide both sides by 2
W^2 + 5W = 150
W^2 + 5W - 150 = 0
Factor
(W +15)(W -10) = 0</span></span>

Roots are W=-15 and W=10.
A negative width is impossible, so W=10
L = 2W + 10
L = 2(10) + 10
L = 30</span></span>
length = 30 feet, width = 10 feet

30*10 = 300</span>

Step-by-step explanation:
Answer:
Cos P = 12/37
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
Cos theta = adj / hyp
cos P = 24 / 74
Cos P = 12/37
