Question

In △ABC, AB=9.2 ft, BC=11.9 ft, and m∠B=27°.



What is the area of △ABC?



Enter your answer as a decimal in the box. Round only your final answer to the nearest hundredth.

Answer 1

Area = 1/2 · AB · BC · sin∠B = 0.5(9.2)(11.9)sin27° ≈ 54.74·sin27° ≈ 54.74·0.45399 ≈ 24.85

Answer: 24.85 ft²
