Answer 1

This is it
sorry for rough work
Have a nice day

Answer 2

solution:

given: the coordinates of 3 sides of a triangle are: A(0,7), B(5,0), C(0,0)

the height of the triangle = coordinate of y axis =5 uniits,
the base of the traingle =coordinates of x axis=7units
Ar(ABC)= 1/2x b x h
              =1/2 x7x5
              =35/2=17.5 sq.units
