What is the area of this polygon? 28.5 units² 34.5 units² 37.5 units² 40.5 units² 6 sided polygon on a coordinate plane with ver

LUCKY_DIMON [66]

Answer:

Option B.

Step-by-step explanation:

The given vertices of the polygon are (-6,-2),(-5,1),(-1,4),(1,1),(5,3),(1,-2).

We need to find the area of the polygon.

Plot the given vertices and on a coordinate plane and draw the polygon. Divide the polygon in 4 parts as shown below.

Area of rectangle is

$A=length\times width$

Area of triangle is

$A=\dfrac{1}{2}\times base\times height$

Area of each figure is

$A_1=\dfrac{1}{2}\times 1\times 3=1.5$

$A_2=\dfrac{1}{2}\times 6\times 3=9$

$A_3=\dfrac{1}{2}\times 4\times 3=6$

$A_4=6\times 3=18$

Area of polygon is

$A=A_1+A_2+A_3+A_4$

$A=1.5+9+6+18=34.5$

The area of polygon is 34.5 units².

Therefore, the correct option is B.

What is 20% off of 35

vodomira [7]

An easy way to find the precentage to to tuen the precentage to a decimal, in this case 20%=0.2, now multiply 35 by 0.2

35x0.2=7!

So 20% of 35 is 7$!

Another way to solve is to take 10% of 35, which you can find by just movig over the decimal (35-$3.50) now just add it together! 3.5+3.5=7$!!

Hope I helped!

harina [27]

How many times do 15 minutes fit into one hour? 4 times: 4*15=60 mins.

So that means that 4 times per hour 10 flights appear, and in total 4*10=40 planes arrive over one hour!
