Question

The length of a rectangular field is one more than twice of the breadth. What is its area if the breadth is $x$?

• A. $2x-1$
• B. 2$x^2$ - $x$
• C. $x^2$ + $2x$
• D. 2$x^2$ + $x$

Answer 1

The correct option is D

2$x^2$ + $x$

Breadth = $x$
Length = $2x+1$
So, Area = length $\times$ breadth
$=(2x+1)\times x$
$=(2x\times x)+(1\times x)$
$=2x^2+x$
