Thank you for the question Flo3s!
For the key worlds you are looking for is "2 1/2 miles" and "approximate"
The closest answer you would get is 13,000 feet. The actual answer is 13,200 feet. But with this we are just estimating.
1 mile = 5280' (feet)
Final Answer:
<em>13,000 feet</em>
Answer: base a=2ft
height hₐ=5ft
Step-by-step explanation:
use equation for area of triengle
A=a*hₐ/2
hₐ-height of tringle
a-base of triangle
hₐ=a+3
A=a(a+3)/2
2A=a²+3a
A=5ft
2*5=a²+3a
a²+3a-10=0
a=(-3±√9+40)/2
a=(-3±7)/2
a=-5ft
a=2 ft
hₐ=2+3=5ft
