Question

Area of a triangle with base b and height h
= ______ x (area of a parallelogram with base b and height h)

• A. $\frac{2}{3}$
• B. $\frac{1}{2}$
• C. $\frac{1}{3}$
• D. $\frac{3}{4}$

Answer 1

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

Area of a triangle with base b and height h
$=\frac{1}{2}\times base\times height=\frac{1}{2}\times b\times h$

We know that area of a parallelogram of base b and height h
= base x height
= b x h

Therefore, area of the triangle
$=\frac{1}{2}\times \text{area of parallelogram}$
