Question

a farmer is building a fence around the field he just bought. the field is a rectangle with sides of 90 feet and 20 feet. how much fencing does he need? the farmer needs \\(\square\\) of fencing. (type an integer or a decimal) square feet feet

Explanation:

Step1: Recall the perimeter formula for a rectangle

The perimeter \( P \) of a rectangle is given by \( P = 2\times (l + w) \), where \( l \) is the length and \( w \) is the width.

Step2: Identify the length and width

Here, \( l = 90 \) feet and \( w = 20 \) feet.

Step3: Substitute the values into the formula

\( P = 2\times(90 + 20) \)
First, calculate the sum inside the parentheses: \( 90 + 20 = 110 \)
Then, multiply by 2: \( 2\times110 = 220 \)

Answer:

220 feet
