The length of your desk is 16 in. more than its width. the perimeter is 104 in. what are the dimensions of your desk?

Step-by-step explanation:

Let us call the width of the rectangle "x." Since the length of the rectangle is five less than twice its width," we can express the length of the rectangle as 2x - 5 (since 2x = twice the width and - 5 indicates "five less").  

***

Now, using x as the width and 2x - 5 as the length, we can create an equation. We know that the perimeter is 86 feet, and the perimeter of a rectangle is the same thing as adding up its sides together: length + length + width + width, or 2*length + 2*width. Thus, we can create the equation

2(length) + 2(width) = 86

Substituting in our expressions for width and length, we get

2(2x - 5) + 2(x) = 86

Now we can just solve for x

2(2x - 5) + 2x = 86

Distribute: 4x - 10 + 2x = 86

Add like terms: 6x - 10 = 86

Add 10 to both sides: 6x = 96

Divide both sides by 6: x = 16

answer: .64
