1. width : length = 3 : 1
Let width = 3x, while length = x.
Perimeter = 3x + 3x + x + x
40 = 8x
x = 5 ... Substitute into width = 3x.
width = 3(5) = 15 units
2. Number of pieces of rope that can be cut = � = 28
Therefore, 28, which is the greatest number of pieces of rope that can be cut from a piece of 8-meters-long rope.
