Question

Plot the points A(4,0),B(4,4),C(-3,0) join A.B. and ac find the area of triangle ABC

Answer 1

Step-by-step explanation:

The area of triangle when coordinates of vertices are given is ,

Area =

|Ax(By-Cy)+Bx(Cy - Ay) +Cx (Ay-By)|

/2

let the coordinates of vertices are,

A(4,0) = (Ax, Ay)

B(4,4) = (Bx, By)

C(-3,0)= (Cx ,Cy)

Area

= | 4 (4-0)+4(0-0)+(-3)(0-4)|/2

=| 16 + 0 + (-3)(-4)| / 2

= | 16 + 0 + (12)| /2

= 28

Therefor Area of triangle is

28 squnit

Answer 2

Answer:

14 units sq.

Step-by-step explanation:

• Area of Triangle =1/2×b×h=1/2×7×4=14 units sq.
