Question

Area of the triangle considering BC as a base is ________.

• A. $15c{m}^2$
• B. $36c{m}^2$
• C. $11c{m}^2$
• D. $9c{m}^2$

Answer 1

The correct option is A $15c{m}^2$

In the given triangle ABC:
height, h is AD = 6 cm,
and the base, b is BC.
Length of BC = BD + DC = 3 cm + 2cm = 5 cm
$\therefore$ base = 5 cm

Area of a triangle = $\frac{1}{2}\times base\times height$
= $\frac{1}{2}\left(5\right)\times \left(6\right)$
= $5\times 3$ = $15c{m}^2$
