100.53+80 = 180.53(rounded)

32pi+80 (not rounded)

Step-by-step explanation:

Triangle area = 1/2 b*h

Semi circle = (pi r^2)/2 - radius= diameter/2

h= 10 m

b=16 m

1/2*16*10

8*10

80 m

Semi circle

(pi8^2)/2

32pi

100.53 (rounded)

Add triangle +semicircle.

100.53+80 = 180.53(rounded)

32pi+80 (not rounded)
