Question

Create a problem that would have the answer 3x+12

Answer 1

Problem:

Consider a rectangle such that the length of the rectangle is 12 more than thrice its width. Find a formula for the length in terms of its width. Take width as 'x'.

Explanation:

Consider a rectangle such that the length of the rectangle is 12 more than thrice its width. Find a formula for the length in terms of its width.

Let the width be 'x'.

Therefore, as per question, length is 12 more than thrice the width.

Thrice the width means
`3x`. 12 more means adding 12 to the result.

Therefore, the length of the rectangle is
`3x+12`

So, the above question expresses the length of the rectangle as
`3x+12` which is the required answer.
