Solution

The correct option is D
2 + x

Breadth = x

Lenght = 2x + 1

So area = $l e n g h t \times b r e a d t h$

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

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

= $2 x^{2} + x$

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

The correct option is D 2 + x Breadth = x Lenght = 2x + 1 So area = lenght×breadth = (2x+1)×x = (2x+1)×(1×x) = 2x2+x

The correct option is D
2 + x

Breadth = x

Lenght = 2x + 1

So area = $l e n g h t \times b r e a d t h$

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

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

= $2 x^{2} + x$
