is 3, 3) The perimeter and the area of the rectangule are 18 feet and 18 square feet, respectively.
Step-by-step explanation:
Let be a rectangle with a length of feet and a width of 3 feet. The area (
), measured in square feet, and perimeter (
), measured in feet, formulas are, respectively:
(Eq. 1)
(Eq. 2)
1) Now, we assume that , then we reduce the system of linear equation into a sole linear equation:
(Eq. 3)
2) We proceed to solve for :
The value of is 3.
3) Lastly, we obtain the values of the perimeter and area:
The perimeter and the area of the rectangule are 18 feet and 18 square feet, respectively.
