Answer:
63,360 feet
Step-by-step explanation:
1 mile = 5280 ft
* 12 *12 (multiply 12 to both sides)
------------------
12 miles = 63,360 ft
The perimeter of the equilateral triangle will be 76.2 in
<u>Explanation:</u>
Altitude of an equilateral triangle, H = 22 in
Perimeter, p = ?
Let a be the side of the triangle
We know:
Perimeter = 3a
P = 3 X 25.4 in
P = 76.2 in
Ok, so after you do -8a+5a, you also have to do 6 -35, getting the equation
-29-3a
If the 0 is in the numerator, the value is 0
if the 0 is in the denominator, the value is undefined
so 0/8 = 0
and 3/0 = undefined
The total area would be 9 1/4 multiplied by 8 4/5 which would equal 81.4 inches
