1st step. Calculate the area of the parallelogram

We can use the following formula:

$A=b\cdot h$

where,

base, b = 9 km

height, h = 5 km

Therefore,

$A=9\cdot5=45$

The area of the parallelogram is 45 km^2

2nd step. Calculate the area of the triangle

Let's use this formula:

$A=\frac{b\cdot h}{2}$

where,

base, b = 6 km

height, h = 3 km

Therefore,

$A=\frac{6\cdot3}{2}=9$

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

$r=\frac{A_P}{A_T}=\frac{45}{9}=5$

Answer: the area of the parallelogram is 5 times greater than the area of the triangle.

Pls help <br> How do u find the area of this figure

Katen [24]

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.
