Answer:
c
Step-by-step explanation:
When we know two sides and the included angle, there is a formula we can use.
We know angle C = 35º, and sides a = 20cm and b = 19.5cm.
using the formula
Area =(½)ab sin C(angle)
Put in the values we know:
(20×19.5÷2)×sin(35)=
111.8474050885 cm^2
rounded = 111.85 cm^2
answer is c
