Answer:
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.
Answer:
Step-by-step explanation:
Area = 35*100*2 + 50*100*2 + 50*35*2
= 7000 + 10000 + 3500
= 20500 cm2
64/3274=0.019547954
Hope this helps.
