Answer: No
Step-by-step explanation:
Complementary means angles add up to 90 degrees.
Supplementary means angles add up to 180 degrees.
Since Supplementary doesn't add up to 180 degrees, the answer is false.

Answer:
139.36
Step-by-step explanation:
first you do 8*8 because that would be the area of the square part 
8*8=64
then find the area of the semicircle 
first the Radis of it is 4 because 8/2=4
A=3.14R^2/2
3.14*4^2/2
3.14*16/2
50.24/2
25.12
now because there are 3 of the semicircles you do 
25.12*3
75.36
then you add the 64 from the square to get your answer 
75.36+64
139.36
