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.
To find this, you have to cut the figure into familiar shapes. In this case, you can cut it into two rectangles. When you cut it, there is a missing measurement, which is the length for the small rectangle. To find that, you subtract the other two lengths given, which is 8 and 6, and thats the length for the small rectangle. Then you do l•w for both shapes.
1/5(100x - 105y + 70) = 20x -21y + 14
Answer: NO
Step-by-step explanation: The sandwiches are at different angles, so you would need two different cuts to make two equal parts each.
