Step by step solution

01

– Given information.

According to the figure provided of a rectangle in the question, the base is 2n+10 and the height is12.

02

– Write the concept.

The area of the rectangle is given by:

Area=12脳Base脳Height

03

– Determine the area.

Substituting the values of base and height we get,

Area=12Base脳Height=12脳(2n+10)脳12[Divide]=6(2n+10)[Multiply]=12n+60
