Question

a farmer is building a fence around the field he just bought. the field is a rectangle with sides of 70 feet and 20 feet. how much fencing does he need?
the farmer needs
of fencing. (type an integer or a decimal)

Explanation:

Step1: Recall the perimeter formula for a rectangle

The perimeter \( P \) of a rectangle is given by the formula \( P = 2\times (length + width) \).

Step2: Identify the length and width

Here, the length of the rectangular field is 70 feet and the width is 20 feet.

Step3: Substitute the values into the formula

Substitute \( length = 70 \) and \( width = 20 \) into the formula: \( P = 2\times(70 + 20) \).
First, calculate the sum inside the parentheses: \( 70 + 20 = 90 \).
Then, multiply by 2: \( 2\times90 = 180 \).

Answer:

180
