Question

The area (in sq. units) of the given figure is expressed as:

• A. $2n+1$
• B. $n+2n$
• C. $n^2+n$
• D. $n^2+2n$

Answer 1

The correct option is D $n^2+2n$


The given figure is a rectangle whose
length = (n+2) units and breadth = n units

Area of a rectangle = length $\times$ breadth
= $(n+2)\left(n\right)$
= $(n^2+2n)$ sq. units
