Suppose P, Q, and R are points in the plane such that PQ = 1.8, PR = 8.2 and angle PQR = 90 degrees. What is the area of angle PQR?

Angles don't have "areas "

 

The area of the triangle is   PQ * QR / 2  =  [1.8 * 8 ]  / 2  =  7.2 units^2

now that you know the other side is 8 simply do 8 * 1.8 = 14.4 

but remember since its a triangle you have to halve it which is 7.2
