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

Answer:
No
Step-by-step explanation:
plug the numbers into Pythagorean theorem
c^2 =a ^2 + b^2
28^2 = 20^2 + 19^2
784 = 400+361
784 = 761
No its not
