Question

A rectangle has a length that is 12 centimeters longer than its width. Let x represent the width of the rectangle. Which of the following would represent the length of the rectangle?

Answer 1

I can't see your answer options, but the answer to this question is x + 12 cm.

We can find this because if the length is 12 cm longer than the width, and the width is 'x' cm, the length has to be x + 12 cm, because this is how you represent something being 12 more than a width. For example, 12 more than 6 is 12 + 6 = 18.

I hope this helps!
