<u>Answer:</u>
The amount of fabric needed to cover the pyramid is .
<u>Step-by-step explanation:</u>
Given, the lantern is in the shape of a square pyramid. And the lantern has to be covered by a fabric. So, the amount of fabric needed to cover the lantern can be calculated by the following formula,
where p is the perimeter of the base of the pyramid and l is the slant height.
Since, it is given that it is a lantern, the area to be covered with the fabric is its L.S.A (Lateral Surface Area) leaving the base where the lamp is lit. So, the L.S.A of the pyramid is equal to the amount of fabric required to cover the lantern.
We have that

Answer : The horizontal distance traveled by a person is, 5630 ft
Step-by-step explanation :
To calculate the horizontal distance traveled by a person we are using Pythagoras theorem.
Using Pythagoras theorem:
Given:
Hypotenuse = 5750 ft
Perpendicular = 1170 ft
Now put all the values in the above expression, we get the value of base.
Therefore, the horizontal distance traveled by a person is, 5630 ft
This is a two step word problem so first your gonna have to subtract 320-50= 270 then divide to find your final answer so 270 divided by 8 is 33.75
