(100 POINTS) Sue has to cut her grandma's grass this weekend and wants to know exactly how much area she will be cutting. Calculate the area of the polygon. Be sure to show all your work and explain your answer.

600.5

Step-by-step explanation:

Below I drew a bunch of lines and seperated this weird shape into two triangles and a rectangle. We can now calculate the area of these three shapes and add them for a total area

Let's start with the two triangles

The area for a triangle is .5*b*h

For the leftmost triangle the area is .5*25*25= 312.5

The area for the southern triangle is .5*8*8=32

The area for the rectangle is: 8*32=256

Add these together and get 312.5+32+256=600.5

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
