Question

Find the base of a triangle whose area is $220c{m}^2$ and height is $11cm$.

• A. $40cm$.
• B. $20cm$.
• C. $50cm$.
• D. None of these

Answer 1

The correct option is A $40cm$.

Area of a triangle$=\frac{1}{2}\times base\times height$

So, $220c{m}^2=1/2\times base\times 11$

$⟹base=\frac{220\times 2}{11}=40cm$
