Question

The vertices of a triangle are A(0, 0), B(3, 8), and C(9, 0). What is the area of this triangle?

Answer 1

Answer: 36 units squared.


Explanation:
Area of a traingle is given by,

| 0.5{x1(y2-y3) + x2(y3-y1) + x3(y1-y2)} |

Accepting the values of the coordinates in x's and y's,

x1 =0, y1=0

x2=3, y2=8

x3 =9, y3=0

= | 0.5 × (-72)|
= 36 unit squared.

Answer 2

Answer:

36

Step-by-step explanation:

(formula for area for coordinates geometry is applied)

1/2|( put in the coordinates tht they give u) |

1/2|-72|

1/2 (72)

=36
