Step-by-step explanation:
The area of a triangle is given by
where
b is the base
h is the height
Here we have an equilateral triangle, which has the 3 sides of the same length.
Let's call L the length of one side.
We know that the perimeter of the triangle is
p = 9 in
The perimeter is the sum of the three sides, so:
Therefore, we find the length of the side:
Therefore the length is the base of the triangle,
The height can be calculated by considering half triangle: the hypothenuse is equal to L, while one side is equal to half the base (b/2), therefore the height is given by Pythagorean's theorem:
Therefore, the area of the triangle is:
Answer:
Final amount after 4 years will be $5518.
Step-by-step explanation:
From the given question Principal amount in the account of Stan = $4706
and we have to calculate amount after 4 years with 4% interest compounded quarterly.
Formula will be final amount
Here A' = $4706
t = 4 years
n = number of times compounded = quarterly that will be 4
r = .04
So the final amount after four years will be $5518.
