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
• C. + 2x
• D. 2 + x

Answer 1

The correct option is D

2 + x

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