Question 723550: The perimeter of a rectangle is 20 inches. If the length is 4 more than the width, find the width of the rectangle.
Data:
Perimeter of rectangle = 20 inches
Let Width of rectangle be 'x'
then, Length of rectangle = 4+x
Solution:
As, Perimeter of rectangle = 4*length
20 = 4*(4+x)
20 = 16+4x
20-16 = 4x
4 = 4x
4/4 = x
1 = x
or x = 1 Answer!
