Answer:
The first one is correct
Step-by-step explanation:
You can multiply the base and perpendicular height to find the area.
Answer:
Do u have answer choices?
Height covered by the plane=h= 500 feet
Distance covered by the plane along the ground=d= 2 mile
Now, convert the mile into feet,
1 mile = 5280 feet
2 mile = 10560 feet
Now, use the formula
h= d tanθ
tanθ= h/d
tanθ= 500/10560
tanθ= 25/528
Take the tan⁻¹ on both side,
θ= tan⁻¹(25/528)
θ =2.71°
8 × 5 = 40
So the border has to be 40 feet.
Hope this helps!
Work:
length × width = answer
length = 8
width = 5
answer = 40
