Question

The three vertices of ∆ABC are A(1,4) , B(-2,2) , C(3,2) . Plot these points on a graph paper and calculate the area of ∆ABC .​

Answer 1

in triangle ABC

height =2 cm

base = 5cm

area= 1/2* base *height

= 1/2*5*2

= 5cm²

Answer 2

in triangle ABC

height =2 cm

base = 5cm

area= 1/2* base *height

= 1/2*5*2

= 5cm²
