Trigonometric area formula: area = what is the area of triangle pqr? round to the nearest tenth of a square unit. 70.5 square units 111.3 square units 185.4 square units 222.5 square units

The complete question in the attached figure

we know that
When we know two sides and the included angle the formula for calculate the area is
Area=(1/2)*a*b*sin C
in this problem
let
a=20
b=12
C=68°
Area=(1/2)*20*12*sin 68°------> Area=111.26 units²-----> Area=111.3 units²

the answer is
111.3 units²
