#### Solutions

Chapter 1.6, Problem 39E
To determine

## To find: The length and width of rectangular garden.

Expert Solution

The width of rectangular garden is 35 ft and length is 25 ft.

### Explanation of Solution

Given:

The length of garden is 10 ft more than its width.

The area of the garden is 875ft2 .

Calculation:

Let the width of garden be x.

Tabulate the given information into the language of algebra.

 In words In Algebra Width of garden x Length of garden x+10

Model the equation for the above information.

length×width=Areaofgardenx×(x+10)=875

Simplify the above equation for x,

x2+10x=875(Expand)x2+10x875=0(Subtract875)(x+35)(x25)=0(Factor)x=35,x=25(Zero-productProperty)

The width of the garden must be a positive number, so the width of garden is 25 ft.

Length of rectangular garden is,

Length=x+10=x+25=35

The length of garden is 35 ft.

Thus, the width of rectangular garden is 35 ft and length is 25 ft.
