Question

Find the area of a triangle whose base is 4 cm and corresponding height is 12 cm long.

• A. $18c{m}^2$
• B. $24c{m}^2$
• C. $12c{m}^2$
• D. $9c{m}^2$

Answer 1

The correct option is B $24c{m}^2$

Area of triangle $=\frac{1}{2}\times base\times height$
$=\frac{1}{2}\times 4cm\times 12cm$
$=24c{m}^2$
