In the accompanying figure, triangle abc has coordinates a(0,3), b(7,3), c(7,7). what is the area of triangle abc in square units?

We know area of triangle =

In triangle ABC , AB is the base and BC is the height

Now we find the distance between A and B

Distance formula is

A(0,3), B(7,3)

Distance AB =

= = 7

B(7,3), C(7,7)

Distance BC =

= = 4

area of triangle =

area of triangle =

= = 14
