Answer:
19 units.
Step-by-step explanation:
Let the width be x units
The length will be 2x - 3 units
The perimeter is 60 units;
Perimeter is given by 2(width) + 2(length)
2(x) + 2(2x - 3) = 60
2x + 4x - 6 = 60
6x = 66
Dividing through gives;
x = 11 units
So the width is 11 units;
The length is 2(11) - 3 = 22 - 3 = 19 units
