Answer:
Sergio's strategy was to multiply the sum of the length and width of the rectangle by 2. This was one correct way to find the perimeter of the rectangle.
Jamie's strategy was to add the given measurements of the length and width of the rectangle together. This was another correct way to find the perimeter of the rectangle.
Karina's strategy was to multiply the given length of the rectangle by 2 and add this product to the width of the rectangle. This was NOT a correct way to find the perimeter of the rectangle, as it did not follow the formulas to finding the perimeter of a rectangle: l + w + l + w, or 2(l + w) and furthermore formulas that explain the same thing. Karina only multiplied the length by 2 and did not account for the width of the retangle which she should have done as well.
Ethan's strategy was to multiply the width by 2, multiply the length by 2, and add these two products together to find the perimenter. This final strategy was correct, and can be used to find the perimeter of the rectangle.
Hope this helps you! I love doing math, so enjoy!
The answer is D
Make it into improper fraction
Then flip 2/5 to 5/2 reciprocal
Multiply
0.05 of any unit (including a pound) is as much as 5/100. We can also simplify it to <u>1/20</u>, so probably that's the answer you're looking for.
I hope it will help you :)
96 because it is the only one that cant be rooted evenly
The answer would 282.74km²
