Question

Find the area of the triangle. Round your answer to the nearest tenth.

a. 742.9 yd2

b. 1,458 yd2

c. 1,323.8 yd2

d. 661.9 yd2

Answer 1

Use A = (ab•sin C)/2.

A = (54•54)•sin(27)/2

A = 661.9181486203

We now round off to the nearest tenths, which means to 1 decimal place.

A = 661.9 yards^2
