Answer:
area = 1/2 x base x perpendicular height
= 1/2 x 4 x 4 = 8 unit square
Step-by-step explanation:
Point A (2,3) and point B (6,3) lie on a line parallel to the X axis by 3 units ( as Y is 3 )
AB = 6-2 = 4 units
Point C (4,7) . 4 is the centre of the line AB. Point C is 7 units above X axis and 7-3= 4 units above line AB.
perpendicular height of point C = 7-3= 4 units
area = 1/2 x base x perpendicular height
= 1/2 x 4 x 4 = 8 unit square
