Question

A farmer has a rectangular field, which measures 100 feet for the length and w feet for the width. If the perimeter is the sum of all four sides of the field, what is an expression for the perimeter of the field? Simplify.

w + 100 + w + 100


2w + 200


4w


2w + 100 + 100

Answer 1

2w + 200.

Explanation:

The perimeter = 2L + 2w where L = the length and w = the width.

So here, P = 2(100) + 2w

= 200 + 2w.

Answer 2

The second one

Explanation:

Perimeter = Length + Length + Width + Width

Perimeter = 2L + 2W

Perimeter: 2W + 100 + 100

Perimeter: 2W + 200
