Question

Plot the points A(2,5)B(-2,2)C(4,2) ON GRAPH PAPER JOIN AB BC AC AND CALCULTE THE AREA OF TRIANGLE

Answer 1

Area of the triangle=9 square units

Answer 2

struct of line AM which is perpendicular to BC

area of triangle ABC = 1/2 × B×h

= 1/2×BC×AM

SO ON Further calculation we get

area of triangle ABC = 1/2×6×3

area of triangle ABC = 9 sq. units
