Answer:

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:
3 7/9
Step-by-step explanation:
we have
3.77777... -----> is a repeating decimal
Let
x=3.7...
so
10x=37.7...
10x-x=37.7...-3.7...
9x=34
x=34/9
Convert to mixed number
34/9=(27/9)+((7/9)=3+(7/9)=3 7/9
