Polystyrene is a petroleum-based plastic made from the styrene monomer. Most people know it under the name Styrofoam, which is actually the trade name of a polystyrene foam product used for housing insulation. Polystyrene is a light-weight material, about 95% air, with very good insulation properties and is used in all types of products from cups that keep your beverages hot or cold to packaging material that keep your computers safe during shipping.

good job! u did it!

Congrats!!! So proud of u!!! :)

-100/-5 = 20

your welcome! Anytime! :)

Alrighty- ethan! I figured it out!

The area of a parallelogram is this: Area = (base)(height)

The area of a triangle is this: Area = 1/2(base)(height)

The height of the parallelogram is 8 and the base is 20. Therefore:

Area = (8 cm)(20 cm)

Area = 160 cm^2

The upside down triangle then has a base of 6. We already know that the two bases equal 20, so 20 – 14 = 6. The triangle also has a height of 12.6. So....

Area = 1/2 (6 cm)(12.6 cm)

Area = 1/2 (75.6)

Area = 37.8 cm^2

Now, to find the area of the whole figure, you would just add the two areas together...

160 + 37.8 = 197.8

So, the area of the figure is 197.8 cm^2!!!

me too, ethan! hate his guts! That' why i posted it! lol.
