Step-by-step explanation:

let's find the circumference of the semi circle. as it's a parallelogram opposite sides are equal. therefore 2 semicircles will have the same circumference

circumference of circle = 2pi r

circumference of half circle = half of circle= pi r

circumference of half circle = 22/7 × 4 ( diameter is 8 therefore radius is half of that)

circumference of half circle = 88/7

this image has 2 half circles with same radius

now find the perimeter of total figure

perimeter= 9+ 9+ 88/7 +88/7

= 18 + 176/7

= 18+ 25.14

= 43.14

to nearest tenth place = 43.1

associative property hopes this ! : )
