Answer:
The width of the top surface of the desk is 1.4 feet.
Step-by-step explanation:
1. Let's review all the information given for solving this question:
Length of the top surface of a desk = 5.6 feet
Width of the top surface of a desk= x
2. Let's find the width of the top surface of the desk
Length of the top surface of a desk = Four times the width
5.6 = 4x
5.6/4 = 4x/4 (Dividing by 4 at both sides)
1.4 = x
The width of the top surface of the desk is 1.4 feet.
