Question

The length and breath of a rectangle are 6 cm and 4 cm respectively. Find the height of a triangle whose base is 6 cm and area is 3 times that of the rectangle

• A. $24cm$
• B. $25cm$
• C. $20cm$
• D. $44cm$

Answer 1

The correct option is A $24cm$

Area of rectangle

$=6\times 4$

$=24$

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

$3\times area\left(rec\tan gle\right)=\frac{1}{2}\times 6\times h$

$\Rightarrow 3\times 24=3\times h$

$\Rightarrow h=24$

Height of triangle $=24$cm
