To determine the scale factor used to create the parallelogram on the right, we need to compare the corresponding sides of the two parallelograms.
Let's analyze the given measurements:
- The left parallelogram has side lengths of 1 inch, 3.5 inches, and 5 inches.
- The right parallelogram is created using a scale factor.
To find the scale factor, we can compare the corresponding sides of the two parallelograms.
1 inch (left parallelogram) corresponds to x inches (right parallelogram)
3.5 inches (left parallelogram) corresponds to y inches (right parallelogram)
5 inches (left parallelogram) corresponds to z inches (right parallelogram)
To get the scale factor, we divide the length of the corresponding side of the right parallelogram by the length of the corresponding side of the left parallelogram.
Scale factor = (Length of the corresponding side of the right parallelogram) / (Length of the corresponding side of the left parallelogram)
Using the given measurements:
x inches = 0.7 inches
y inches = ?
z inches = 5 inches
Let's calculate the scale factor for the side 3.5 inches on the left parallelogram:
Scale factor = y inches / 3.5 inches
Now, we can use the scale factor for the side 3.5 inches to find the length of the corresponding side on the right parallelogram:
y inches = Scale factor * 3.5 inches
Similarly, we can calculate the scale factor for the side 5 inches on the left parallelogram:
Scale factor = z inches / 5 inches
And use the scale factor for the side 5 inches to find the length of the corresponding side on the right parallelogram:
z inches = Scale factor * 5 inches
Finally, we can compare the side lengths on the left and right parallelograms to find the scale factor.
Please provide the lengths of the corresponding sides on the right parallelogram to continue the calculation and find the scale factor.
To determine the scale factor, we need to compare the corresponding measurements of the two parallelograms.
In the original parallelogram on the left:
- The length of the horizontal side (base) is 1 inch.
- The length of the diagonal side is 3.5 inches.
In the scaled parallelogram on the right, the corresponding measurements will be proportional to the original parallelogram:
- Let's assume the scale factor is "x".
- The length of the horizontal side (base) in the scaled parallelogram will be 1 inch * x.
- The length of the diagonal side in the scaled parallelogram will be 3.5 inches * x.
According to the given measurements:
1 inch * x = 0.7 inches.
Solving for "x":
x = 0.7 inches / 1 inch
x = 0.7
Therefore, Kamla uses a scale factor of 0.7 to create the parallelogram on the right.
The correct answer is:
