The area of a rectangle is expressed as (12m + 18) square feet. If the width of the rectangle is 6 feet, choose an expression to represent the length of the rectangle.

L = 2m+3

Step-by-step explanation:

The area of a rectangle is found using the formula A=L*W. The area A=12m+18. The width is W=6. The length will be the expression where 6 times it gives 12m+18. The expression is 2m+3 since 6 (2m+3) = 12m+18.
