Question

Find the area of triangle ABC.

• A. $\frac{1}{2}\times AB\times BC$
• B. $\frac{1}{2}\times BC\times AD$
• C. $\frac{1}{2}\times AC\times BC$
• D. $\frac{1}{2}\times BC\times AE$

Answer 1

The correct option is B $\frac{1}{2}\times BC\times AD$

Area of triangle ABC
$=\frac{1}{2}\times Base\times Height$

Area of triangle ABC
$=\frac{1}{2}\times BC\times AD$

AD is the perpendicular dropped to BC from point A.
