represent the following situation with an equation. Do Not Solve. The perimeter of a rectangle is 240cm, and the width is 12 cm. Write an equation to find the length, l

1 answer

Let l represent the length of the rectangle.

The perimeter of a rectangle can be calculated by adding the lengths of all four sides. In this case, we know that the width is 12 cm, so one length of the rectangle will measure l cm and the other length will also measure l cm. The sum of these lengths and the widths on both sides will be equal to the perimeter of the rectangle, which is 240 cm.

Therefore, the equation to find the length (l) is:

2l + 2(12) = 240
