Answer:
9 feet = Perimeter of the triangle.
Explanation:
Here, this question is incomplete and lacks essential data. So, still we will try to figure it out. What we can learn from this question.
So, first of all it talks about perimeter. So, let's understand first, what is perimeter and how it can be calculated for a triangle.
What is Perimeter?
So, Perimeter is actually the distance or path covered by a particular 2 dimensional shape. For example, square, triangle, rectangle.
Furthermore,
In this question, we have been given s = 3 feet. We can say that it is a length of one side of a triangle and triangle must be equilateral triangle having all sides equal to one another.
Equilateral Triangle have all sides equal to one another.
Here, we s1 = 3 so, other sides would be s2 = 3 and s3 = 3
Finally, here is the formula for the calculation of Perimeter of a triangle.
P = a + b + c
where, a, b, c represents sides of the triangle.
P = 3 + 3 + 3
P = 9
Hence, the perimeter of the triangle in this question is 9 feet.
