Question

If sides A and B of a triangle have lengths of 10 and 1 respectively, and the angle between them is `pi/2`, then what is the area of the triangle?

Answer 1

Area of the triangle is `=5` sq units.

Explanation:

Sides `A=10 ; B=1` and angle between them is `/_C = pi/2=180/2=90^0` This is a right angled triangle. So area of the triangle`=1/2*A*B = 1/2*10*1=5` sq units [Ans}
