Question

Find the area of the triangleA) 24 cm^2B) 12 cm^2C) 10 cm^2D) 5 cm^2

Answer 1

The area of a triangle is

Therefore the formula for a rectangle triangle is

$A=\frac{bh}{2}$

Then applying the formula we get

$\begin{gathered} A=\frac{8\cdot3}{2} \\ \\ A=4\cdot3 \\ \\ A=12\text{ cm}^2 \end{gathered}$

The area of the traingle is 12 cm^2, the correct answer is the letter B
