Find the area of QRS. Round the answer to the nearest tenth. A.
10.8 square units
B. 12.4 square units
C. 25.4 square units
D. 50.7 square units

Option C

Step-by-step explanation:

Area of a triangle given with measures of 2 sides and angle between these sides will be,

Area of a triangle =

Here, a and b are two sides of the triangle and C is the angle between these sides.

From the figure attached,

a = 6, b = 9 and m∠C = 110°

Substitute these values in the formula,

Area of ΔQRS =

                        =

                        = 25.37

                        ≈ 25.4 square units

Therefore, Option C will be the answer.
