What is the area of polygon ABCDE?

Mathematics

Answer:

66 cm

Step-by-step explanation:

You can find the area of the rectangle by simply multiplying the sides that are complete and don't touch the triangle. That is equal to 60 cm.

To find the area of the triangle, you first have to find the sides. You can find the first side by subtract the top side of the rectangle from the bottom, which gets us 3 (12-9). Then subtract the left side (5) from the right side (9) (9-5), which gets us 4. That would mean that 3*4*1/2 is equal to 6. 6+60 is equal to 66 cm.

Hope that this helps!

Which is the most accurate description of the polygon?
kherson [118]
Let’s take a look at the definitions of all of these categories of polygon:

A rhombus is a quadrilateral with four equal-length sides

A trapezoid is a quadrilateral with at least one pair of parallel sides

A kite is a quadrilateral with two pairs of equal sides, where those sides are adjacent to each other

A quadrilateral is a four-sided polygon

And let’s compare our definitions with the figure:

- None of the sides of the figure are equal to each other, so we it can’t be a rhombus
- The slopes of all of the sides are different, so the figure can’t have a pair of parallel lines, ruling out the chance that it’s a trapezoid
- That first bullet point also rules out the possibility that our figure is a kite
- Our figure *is* a four-sided polygon though, so it meets the requirements for a quadrilateral

So, the only label that works for this figure is a *quadrilateral*.

The classes at the middle school want to raise money. The sixth grade runs a bake sale for 55 hours and makes $170. The seventh
ANEK [815]
The 8th grade does. All you do is divide each number by the amount of hours worked. So 6th grade 170/55 7th 112/4 and 8th 192/6
In the end its 6th= 3 dollars an hour 7th= 28 dolars an hour and 8th gets 32dollars an hour so they have the highest rate

The ticket price was decreased by 8.75-6=2.75$
to know the percentage of decrease:
percentage=(fraction of decrease/total price) x 100
