Question

the area length of a rectangle is 9 units more than 6 times the width. write and expression of the area of the rectangle

Answer 1

We have the next formula for the area of a rectangle

$A=lw$

where l is the length and w is the width

in our case

l=6n+9

w=n

We substitute the expressions on the formula

$A=(6n+9)n$

Then we simplify

$A=6n^2+9n$

ANSWER

A=6n^2+9n
