Question

The area of a triangle with vertics (0,0) , (2,0) and (0,4) is :

• A. 4 sq.units
• B. 6 sq.units
• C. 8 sq.units
• D. 2 sq.units

Answer 1

Answer:

A. 4 sq.units

$Area = \frac{1}{2}|x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)|$

$\frac{1}{2}|0+2(4-0)+0|=\frac{1}{2}|8|=\frac{1}{2}\times 8=4$
