l=length h=width
l=3h
l-h=8
3h-h=8
2h=8

The length of the rectangle will be 12 units.

The rectangle is a geometrical figure in which opposite sides are equal.

The angle between any two consecutive sides will be 90 degrees.

Area of rectangle = length × width.

Perimeter of ractangle = 2( length + width).

Let say,

Length = l and width = w

Given,

length of a rectangle is 3 times the width

l = 3w

The difference between the length and the width is 8 feet

l - w = 8

By equation 1 and 2

3w - w = 8

2w = 8

w = 4

Substitute into equation 1

l = 3(4)

l = 12 units.

So the length of the rectangle will be 12 units.
