An equilateral triangle has a side length measure that is represented by 2x+4. what is the perimeter of the triangle? and how would i show this in a model?

The perimeter is 6x + 12, and a model example is attached.

All three sides of an equilateral triangle are the same, so multiply the side length by 3 to find the perimeter.

3(2x + 4)

Now distribute the 3.

3 * 2x + 3 * 4

6x + 12

Option: A

Step-by-step explanation:

A sprinkler sprays water over a distance of (r) = 40 feet

Rotates through an angle of (θ) =  80°

80° convert to radians

θ in Radians = 1.396263402

We know that,

Area of sprinkler is

Substitute the given values,

Area of sprinkler is
