Question

 

Write an expression for the area of a rectangle if the length is four times the width plus twelve.

 

Draw your rectangle here, then label the width and length.

Answer 1

L = 4W + 12

Area = W(4W+12).

 

Answer 2

The area of any rectangle is its length times its width. Therefore, area = length X width. Since the length depends on the width and is defined by the width in this problem, let's call the width X. If the length is 4 times longer, that would be 4x+12. So the area would be equal to X times 4X+12.......or 4Xsquared + 12X.
