remember the lot size is 150 ft by 90 ft.
280 feet

486 square feet
480 feet

Explanation:

Step1: Recall the formula for perimeter of a rectangle

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

Step2: Substitute the given values

Given \(l=150\) ft and \(w = 90\) ft. Then \(P=2(150 + 90)\).
First, calculate the sum inside the parentheses: \(150+90=240\).
Then multiply by 2: \(P = 2\times240=480\) ft.

Answer:

480 feet
