Answer:
The dimensions of rectangular table are length = 79 centimeters and width = 261 centimeters.
Explanation:
Given:
The perimeter of the rectangular table is 680 centimeters.
Now, to find the dimensions:
Let, the width of rectangular table be

And the length of the table be

Now, putting the formula of perimeter of rectangle to get the dimensions:
Perimeter = 2(length + width)



By subtracting both sides with 48 we get:

Now, dividing both sides by 8 we get:

So, width of the table = 79 centimeters.
And, length of the table = 24+3×79
= 24+237
= 261 centimeters.
Therefore, the dimensions of rectangular table are length = 79 centimeters and width = 261 centimeters.
