Question 895108: The perimeter of the rectangle shown below is 70 cm. (a) What is the value of “y”? () What is the length of the rectangle? (c) What is the width of the rectangle?
One side is 3y+4 which is the length and y+3 which is the width.

You can put this solution on YOUR website!
You posted another one like this which had included a hyperlink which did not load.

I will try to help on this anyway.

If your dimensions are x and y, then the perimeter is 2x+2y=70; divide members by 2 and you have x+y=35.
y=35-x.

Again, the figure or picture is needed. If width is 3y+4 and length is y+3, then using the simplified perimeter equation,
3y%2B4%2By%2B3=35
4y%2B7=35
4y=28
y=7------Use this to find the value for x.

x%2By=35
x=35-y
x=35-7
x=28-----The other dimension.
