36 square feet because the width would be a and so since the length is 4 times that you can say that the two sides added together would be 5a 30 feet is the parameter which would include all 4 sides but we are only looking for 2 sides so you can divide that by 2 so 5a=15 so divide 15 by 5 and you get 3 so a=3 4a=4 3= 12=length a=3=width length width=area 12*3= 36 square feet

The area of the rectangular deck is 36 square feet. This is calculated by first determining the width and length from the perimeter. The width is found to be 3 feet, and the length is 12 feet, leading to the area calculation of 12 × 3 = 36 square feet .
