Question

plot the points a(2,5) and c(4,2) on a graph paper. join ab ,bc and ac. calculate
area of triangle abc​

Answer 1

Step-by-step explanation:

Given

a(2,5),b(0,0),c(4,2)

$area \: of \: triangle = \frac{1}{2} |x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2)|$

By substituting the coordinates of a,b,c

we get the answer as 8sq.units

or apply Pythagoras theorem
