Question

Write the smallest number which can be shown as a line, rectangle, square and triangle.

Answer 1

We have,

Minimum whole number required to represent a line $=2$

Minimum whole number required to represent a square $=4$

Minimum whole number required to represent a Rectangle $=6$

Minimum whole number required to represent a triangle $=3$

$\Rightarrow$LCM of $(2,3,4,6)=2\times 2\times 3=12$

Hence, $12$ is the correct answer.
