The area of a square is 36 square feet. If each side is lengthened by 4 feet, how could the perimeter of the new square be calculated?
A.
Divide 36 by 4 to get 9. Then add 4 to 9 to get 13 and multiply this by 4 to get the new perimeter.
B.
Divide 36 by 4 to get 9. Then add 4 to 9 to get 13 and multiply this by 13 to get the new perimeter.
C.
An area of 36 means the original square was 6 feet long on a side. Add 4 to 6 to get 10. Then multiply by 4 to get the new perimeter.
D.
An area of 36 means the original square was 6 feet long on a side. So its perimeter was 24 feet. Add 4 feet to this to get the new perimeter.
D.
An area of 36 means the original square was 6 feet long on a side. So its perimeter was 24 feet. Add 4 feet to this to get the new perimeter.
To solve this problem, we need to determine the length of one side of the original square. We know that the area of the square is 36 square feet, so we need to find a number that, when multiplied by itself, equals 36. In this case, the number is 6, as 6 multiplied by 6 equals 36.
Now, we are asked to lengthen each side of the square by 4 feet. This means that the new length of one side of the square will be 6 + 4 = 10 feet.
To calculate the new perimeter, we need to multiply the new length of one side by 4, as the square has four equal sides. Therefore, the new perimeter is 10 * 4 = 40 feet.
Looking at the options provided, option C correctly states the steps to calculate the new perimeter.
