Question

The vertices of a right- angled triangle are A(1,0), B(7.0) and C(1,6). Plot the points A, B and C on the cartesian plane below. Hence find the area of ABC

Answer 1

`A=21`

Explanation:

From the question we are told that:

Co-ordinates

`A(1,0), B(7.0)\ and\ C(1,6)`

Hence Plotting the Cartesian plane we have

Base
`b=7`

Height
`h=6`

Generally the equation for The Area of a Triangle is mathematically given by

`A=(1)/(2)b*h`

`A=(1)/(2)*7*6`

`A=3.5*6`

`A=21`
