Let width of the rectangle be x
Then, length will be (x+14)
Perimeter = 160cm
We know that the formula for the perimeter of a rectangle is: 2(l+w) = P
Now, substituting the values in place of 'l' and 'w', we get:
2(x+14+x) = 160
2(2x+14) = 160
4x+28 = 160
4x = 160-28
4x = 132
x = 33cm
Therefore, the width of the rectangle = 33cm and the width of the rectangle = 33+14 = 47cm
