Final answer:
To find the perimeter of the concrete form, convert all the side lengths to sixteenths, add them together, and then simplify. The perimeter is 109 3/16 inches.
Step-by-step explanation:
The student is asking how to find the perimeter of an irregularly shaped concrete form with four given side lengths: 11 5/16 inches, 36 1/2 inches, 44 1/8 inches, and 16 1/4 inches.
To calculate the perimeter, you simply need to add up all the side lengths together. When dealing with measurements in inches that include fractions, it's often helpful to convert all the fractions to sixteenths to make them easier to add.
Here's the conversion:
11 5/16 inches remains the same
36 1/2 inches converts to 36 8/16 inches
44 1/8 inches converts to 44 2/16 inches
16 1/4 inches converts to 16 4/16 inches
After the conversion, the sum of the lengths will give us the total perimeter.
Now, let's add:
11 5/16 + 36 8/16 + 44 2/16 + 16 4/16 = 108 + 19/16 inches
Since 19/16 is more than 1, we convert this to 1 3/16 to add to the whole number, giving us:
108 + 1 + 3/16 inches = 109 3/16 inches.
Therefore, the perimeter of the concrete form is 109 3/16 inches.
