A carpenter is building a rectangular fence for a playground. One side of the playground is the wall of a building 70 ft wide. He plans to use 340 ft of fencing material. What is the length of the playground if the width is 70 ft? I don't know how I would write this equation. Any help is appreciated!

By knowing that this is a rectangular area we already know 2 sides from 1 measurement.

70ft + 70ft = 140ft of both sides

By taking the total of 340ft you get:

340ft - 140ft = 200ft

Now that there is 200ft left and only 2 sides that are equal to each other we can just divide by 2.

200ft / 2 = 100ft

Now we have the length as 100ft and the width as 140ft.

This will result in a playground fence of 100ft by 70ft.

7days is 168 hours in decimal form it is just 168 there is no decimal form for this because it is like 168.0 and there is no number you are dividing it by for it to be a decimal.hope this
