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. 2x²-x
• C. x²+2x
• D. 2x²+x

Answer 1

The correct option is D

2x²+x

Breadth = $x$

Lenght = $2x+1$

So, area = lenght $\times$ breadth

$=(2x+1)\times x$

$=(2x\times x)+(1\times x)$

$=2x^2+x$
