PLEASE HELP ITS MY TRIMESTER TEST MY MOM WILL KILL ME IF I FAIL! <3 WILL MARK BRAINLIST!

B

Step-by-step explanation:

we have all the sides of the parallelogram, we just need to find the circumference of the semicircle and the diameter is already given. so the final equation should look like this:

(18 x 3.14 ÷ 2) + 27 + 18 + 27 = 100.26

in this case, i took pi as 3.14 because when i used the actual pi number, my answer was 100.27, so i used 3.14.

hence, the answer is B which is 100.26 inches

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
