Question

A trianlge is drawn between two parallel lines 6 cm apart. If the lenght of the base is equal to the distance between the lines, then its area is .

• A. $36c{m}^2$
• B. $18c{m}^2$
• C. $24c{m}^2$

Answer 1

The correct option is B $18c{m}^2$

Given,
PQ || RS
Distance between the two parallel lines = 6 cm = height of the triangle
Also, the length of the base of the triangle = 6 cm
$\therefore Area=\frac{1}{2}\times base\times height$
$\Rightarrow Area=\frac{1}{2}\times 6\times 6=18c{m}^2$
