Question

A field is a rectangle with a perimeter of 1260 feet. The length is 100 feet more than width. Find the width and length of the rectangle field.

Answer 1

To solve this problem you must apply the proccedure shown below:

1. The formula for calculate the perimeter of a rectangle is:

$P=2L+2W$

Where $L$ is the length and $W$ is the width.

2. The length is $100ft$ more than the width, therefore:

$L=W+100$

3. Substitute values into the formula for calculate the perimeter and solve for the width:

$1260=2(W+100)+2W\\ W=265ft$

3. Then, the length is:

$L=265ft+100ft\\ L=365ft$

The answer is: The length is $365ft$ and the width is $265ft$
