Question

The area of a rectangle is 54 square meters. The width is 9 meters long.

Answer 1

A)
`9 *l=54`

Explanation:

The area of a rectangle is w*l=A, where w is the width and l is the length.

In this question, we are given 2 of the variables. We are told that the width is 9 and the area is 54. So, to find the equation that represents this situation, simply plug in the values.

• This gives
  `9 *l=54`.

Then, if needed we can find the length of the rectangle. Through the division property of equality, we know that dividing both sides of the equation maintains the equality of the equation. So, we can divide both sides by 9 to isolate the variable.

• This means that
  `l=6`.
