Find the area of the regular polygon.<br> Round to the nearest tenth.
Keith_Richards [23]

Answer: \text{Area}=110.9 ft^2


Step-by-step explanation:

The given regular polygon has 3 sides, therefore, it is a triangle with all sides equal and called equilateral triangle.

The area of equilateral triangle is given by:-

\text{Area}=\frac{\sqrt{3}}{4}a^2, where a is the side length of equilateral triangle.

Now, the area of given equilateral triangle with sides = 16 ft. is given by:-

\text{Area}=\frac{\sqrt{3}}{4}(16)^2\\\Rightarrow\text{Area}=\frac{\sqrt{3}}{4}(256)\\\Rightarrow\text{Area}=110.85\approx110.9 ft^2

PLEASE! I NEED HELP. ITS VERY EMERGENCY
WITCHER [35]
Here it is:

The first set has (0,1) and (0,5), which assigns to the *same* x, more than one value of *y*. That's not a function. It's a curve. Think about a circle, or instance. It's NOT a function, but it's a curve.

The second one has for each *x* a single *y*

BTW, there's no problem if for *different* x there is the same *y*:

y = 5,

all x, have the same y, equal to 5. That's a function, or y = x^2, etc
