Answer:
[tex]A=21[/tex]
Step-by-step explanation:
From the question we are told that:
Co-ordinates
[tex]A(1,0), B(7.0)\ and\ C(1,6)[/tex]
Hence Plotting the Cartesian plane we have
Base [tex]b=7[/tex]
Height [tex]h=6[/tex]
Generally the equation for The Area of a Triangle is mathematically given by
[tex]A=\frac{1}{2}b*h[/tex]
[tex]A=\frac{1}{2}*7*6[/tex]
[tex]A=3.5*6[/tex]
[tex]A=21[/tex]
