What is the perimeter of the triangle if s=3 feet? Round your answer to the nearest hundredth

9 feet = Perimeter of the triangle.

Step-by-step 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.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.

if x decreases by 4 then y increases by 10
