Answer:
The length is 16 feet.
Step-by-step explanation:
A rectangle is a shape with two different measurements - length and width. Since it has four sides, the width on both sides must be the same and the length on the other two sides must also be the same. In this case, we know that the width of the rectangular patio is 12 feet, which means the opposite side must also be 12 feet, for a total of 24 feet. The perimeter of a shape refers to the measurement of all the sides added together. Since, we know that the total perimeter is 56, we can set up an equation to solve for length: 2L + 24 = 56, where 'L' is equal to length. Using inverse operations to solve for 'L', we subtract 24 from 56 to get 32 and then divide by 2 to get a length of 16 feet.
