Question

The length of rectangular dining hall is twice its breadth. Let $x$ represent the breadth of the hall. What is the area of the floor of the hall in terms of $x$?

Answer 1

Breadth of the hall $=x$ units

Length of the hall $=2x$ units

Area of the floor of the hall $=$ Length $\times$ Breadth

$=\left(2x\right)\times x$

$=2x^2$ sq. units

$\therefore$ Area of the floor $=2x^2$ sq. units
