Area of triangle = 1/2 x AB x perpendicular height
= 1/2 x (3-1) x (5-1)
= 1/2 x 2 x 4
= 4 square units
Gradient of line passing thru B and C is the gradient of line BC. Apply gradient formula using coordinates of B and C:
B =(1, 3) and C= (5, 5)
Gradient= (5 - 3)/(5 - 1) = 2/4= 1/2
= 1/2 x (3-1) x (5-1)
= 1/2 x 2 x 4
= 4 square units
