The perimeter of a rectangle is 900 yards. what are the dimensions of the rectangle if the length is 70 yards more than the width?

First, it would be best to divide each side of the rectangle (4 sides) equally first that is:

900:4= 225

So, now we know each side is 225 Yards first..
Now, since the length is 70 yards longer than the width, we know that:

Length: 225+70= 295

Respectively, we also know that the width is 70 yards shorter since the length is already 70 yards longer:

Width: 225-70=155

Checking (295*2) + (155*2) = 900 Yards

As our final answer, the dimension of the rectangle is 295 yards (Length) by 155 yards (Width)

Hope this help with your studies.
