Answer:

Area = 5 sq ft

Explanation:

Area of a Triangle with Side angle side method is given by the formula given as under


\ Area=(bc \sin A)/(2)

In our problem we are given that


A= 42


\sin 42=0.6691


b=3 \ feet


c=5 \ feet

Putting these values in the formula we get


\ Area=(3 * 5 \sin 42)/(2)


\ Area=(15 * 0.6691)/(2)


\Area=5.01

Hence Area of the Triangle is 5 Sq Ft
