Question

Using definite integration find area of triangle with vertices at a(1,1),b(3,3)and c(4,1)

Answer 1

3 Sq units is the area of triangle with vertices at a(1,1),b(3,3)and c(4,1)

Step-by-step explanation:

vertices

a ( 1, 1)

b ( 3 , 3)

c ( 4 ,1 )

Area of Triangle  =  (1/2) | 1 (3 - 1)  + 3( 1 - 1)  + 4(1 - 3)|

= (1/2) | 2 + 0  - 8|

= (1/2) | -6 |

= 6/2

= 3

3 Sq units is the area of triangle with vertices at a(1,1),b(3,3)and c(4,1)
