Since, the large rectangle was scaled by a scale factor 'k' to form the smaller rectangle,
Scale factor =
=
=
=
Part B
Scale factor =
Therefore, side length of the unknown side = = 2.75 feet
1st step. Calculate the area of the parallelogram
We can use the following formula:
where,
base, b = 9 km
height, h = 5 km
Therefore,
The area of the parallelogram is 45 km^2
2nd step. Calculate the area of the triangle
Let's use this formula:
where,
base, b = 6 km
height, h = 3 km
Therefore,
The area of the triangle is 9 km^2
3rd step. calculates the ratio of the area of the parallelogram to the area of the triangle
Answer: the area of the parallelogram is 5 times greater than the area of the triangle.
