Either use a calculator (the preferred method) or a table (probably located in the back of your book) to get

sin%28132%29=0.743 (note: this value is approximate)


So A=%281%2F2%29%2820%29%2815%29sin%28132%29 then becomes A=%281%2F2%29%2820%29%2815%29%280.743%29


Multiply everything out and simplify to get A=111.45 (which is approximate)
