Below are sample questions representative of the exercises included on this worksheet and related Pre CAL.101 Find the Area of a Triangle Using Trigonometry skill assessments:

Problem 1Difficulty: Mastery

A triangle has sides 18 ft and 2.2 yd with an included angle of 38 degrees. Find the area in square feet, to the nearest tenth.

Solution & Explanation:Convert 2.2 yd to feet: 2.2 yd = 6.6 ft. Then A = 0.5(18)(6.6)sin(38 degrees) = 36.6 square feet.

Problem 2Difficulty: Mastery

A triangle has sides 3.75 m and 2.60 m with an included angle of 1.47 radians. Find the area to the nearest hundredth square meters.

Solution & Explanation:Use A = 0.5ab sin(C). Substitute a = 3.75, b = 2.6, and C = 1.47 radians: A = 0.5(3.75)(2.6)sin(1.47) = 4.85 square meters (rounded as requested).

Problem 3Difficulty: Mastery

A triangle has sides 0.006 km and 4.2 m with an included angle of 41 degrees. Find the area in square meters, to the nearest thousandth.

Solution & Explanation:Convert 0.006 km to meters: 0.006 km = 6 m. Then A = 0.5(6)(4.2)sin(41 degrees) = 8.266 square meters.
