# If sides A and B of a triangle have lengths of 3 and 5 respectively, and the angle between them is (pi)/4, then what is the area of the triangle?

Dec 7, 2015

Area=15/2$\sqrt{2}$

#### Explanation:

Area of a triangle when 2 sides are given with the angle included b/w them is given by:

area=1/2(a*b*sinC)
= 1/2(5*3*1/sqrt(2))
