What is the new perimeter in feet.

Answer to Problem 49CCR
Explanation of Solution
Given information:
Tates flower garden has a perimeter of 25 feet. He plans to add 2 feet 9 inches to the width and 3 fet 9 inches to the length.
Concept Used:
Rules of Addition/ Subtraction:
- Two numbers with similar sign always get added and the resulting number will carry the similar sign.
- Two numbers with opposite signs always get subtracted and the resulting number will carry the sign of larger number.
Rules of Multiplication/ Division:
- The product/quotient of two similar sign numbers is always positive.
- The product/quotient of two numbers with opposite signs is always negative.
Calculation:
In order to find the new perimeter in feet, first convert 2 feet 9 inches to 2.75 feet and 3 feet 9 inches to 3.75 feet, and then new perimeter is equal to multiplying 2 to the increases length and increases width and then adding old perimeter on it and solving it as shown below:
Thus, the new perimeter is 38 feet.
