Answer:

26.28

Step-by-step explanation:

First, add the side lengths of what you know. 6 + 6 + 8 = 20.

Then, find the circumference of the circle, BUT make sure you divide it by 2 because it is a semicircle in the figure.

The formula is 2[tex]\pi[/tex]r, so plug in the radius = 2

So the circumference is 4[tex]\pi[/tex], then divide by 2 to get 2

20 + 2[tex]\pi[/tex] = 26.28

Step-by-step explanation:

we know all 3 values of trapezium length. so let's find out the circumference of half circle

circumference of circle= 2pi r

circumference of half circle = (180/360)× 2pi r

therefore it's equal to pi r

circumference = 22/7 ×2 (diameter is 4 so radius is 2)

circumference of half circle = 44/7

Total perimeter of the figure= 8+6+6+(44/7)

=20 + 6.28

= 26.28

Round of to nearest tenth place = 26.3
