Question

The length, in inches, of a box is $3$ inches less than twice its width in inches. Which of the following gives the length, $l$ inches, in terms of the width, $w$, inches of the box?

• A. $l=\frac{1}{2}w+3$
• B. $l=w+3$
• C. $l=w-\frac{3}{2}$
• D. $l=2w-3$
• E. $l=w-\frac{3}{2}$

Answer 1

The correct option is D $l=2w-3$

Let width be $w$ and length be $l$

According to the question:

Length is $3$ inches less than twice of width

Twice of width $=2w$

$\therefore l=2w-3$
