Answer:
perimeter of a rectangle is the sum of both lengths and both widths, which is equal to 54 meters. Let's call Length L and Width W.
The question is saying this: L = 3 meters + 3(W). We have 2 variables, which means we need at least 2 equations to solve. So far we have one, our second equation is from the perimeter.
2 lengths + 2 Widths = 54. Now, it's just a plug and chug.
2(3 + 3W) + 2W = 54.
6 + 6W + 2W = 54
8W = 48
W=6
L = 3 + 3(6) = 21
To double check: 2(21) + 2(6) = 42 + 12 = 54
The Width is 6 meters, and the Length is 21 meters

Step-by-step explanation:
Given,
We need to find the length of the rectangle.
According to the formula,
Perimeter of the rectangle = 2 × (Length + Width)
So,
54 = 2 (Length + 12)
54 = 2 × Length + 24
54 - 24 = 2 × Length
30/2 = Length
15 m = Length
