Answer:
The rectangle is 11cm by 33cm long
Step-by-step explanation:
The easiest way to solve this is in a diagram, and that is how I'll explain the answer.
If you have a rectangle, where the length is 3 times the width, you can label the sides as x, and as 3x.
Now there are 2 sides labeled as 3x, and 2 sides labeled as x.
Since we are dealing with the perimeter of the rectangle, add all the values together to get 8x. since this value also represents the perimeter, we can set it equal to 88.
We then divide both sides by 8, to get x=11.
Then, plug in the value of x to each side,
So the width was x, and now is 11, and the length was 3x, and now is 33
