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.
