just add up the lengths of the three sides

length of AB =

\sqrt{ {2}^{2} +  {6}^{2}  }

length of BC

\sqrt{ {7}^{2} + {3}^{2}   }

length of CA

\sqrt{ {5 }^{2}  +  {1}^{2} }

(yeah, it's with pythagoras)

let's sum everything up

length AB+BC+CA = 21.011

the units would just be considered as "length units" I guess

hope it helps. have a nice day.

feel free to ask questions.

and maybe, if I'm feeling really nice and a lil bored, i leave greeting answers under yours to enable posters to give gives brainliests. if theres no 2and answer at least

PLEASE HELP WILL GIVE 1ST RIGHT ANSWER AS BRAINIEST The radius of a circle is x+6 and its diameter is 3x+5. What is the circumfe
Rzqust [24]

Answer:

The circumference of the circle = 26π unit.

Step-by-step explanation:

Given:

Radius of the circle, r = "x+6"

Diameter of the circle, d = "3(x)+5"

We have to find the circumference of the circle in terms of pi.

Formula to be used:

Circumference of a circle = 2πr or πd

As we know that:

Radius = Half of diameter

So,

⇒ radius=\frac{diameter}{2}

⇒ x+6=\frac{3x+5}{2}

⇒ 2\times (x+6)=\frac{3x+5}{2}\times 2

⇒ 2x+12=3x+5

⇒ 12-5=3x-2x  ...<em>Arranging variables and constants. </em>

⇒ 7=x

Plugging x = 7 we will find the radius and the diameter.

⇒ Radius = "x+6" = "7+6" = 13

⇒ Diameter = "3(x)+5" = 3(7)+5 =26

Lets find the circumference of the circle.

⇒ Circumference = 2\pi r= 2\pi (13) = 26 \pi        Or

⇒ Circumference = \pi d=\pi (26)=26\pi

The circumference of the circle = 26π unit.
