The point A has co-ordinates (-4,6) and the point B has co-ordinates (7,-2).

Serhud [2]

Answer:

√185 or 13.60 units to the nearest hundredth.

Step-by-step explanation:

For the points (x1,y1) and (x2,y2) the length between the points is given by:

L = √ [ (x2-x1)^2 + (y2-y1)^]

So here we have:

Length of AB √ [ (7- - 4)^2 + (-2 - 6)^2]

= √ (121 + 64)

= √185.

I hope this helps you

radius=diameter/2

radius=1,5/2

radius=0,75

Area=pi. r^2

Area=3,14. (0,75)^2

Area=1,76

Find the area of this irregular polygon.

Rainbow [258]

Answer:

970m^{2}

Step-by-step explanation:

This polygon can be divided in two figures: one is a triangle, an the other one is a square.

We'll begin calculating the triangle's area, using the following formula:

$At= \frac{b.h}{2}$

Where:

$H= height = 30 m$

$B = 9 m + 9 m + 20 m = 38 m$

As you can see, I added both sides of the triangle that measure 9 m and also the lenght of the square that measures 20 m! This added up is what the base of the triangle measures on total.

$At= \frac{38 m .30 m}{2}$

$At= \frac{1140 m^{2} }{2}$

$At= 570 m^{2}$

Now we are going to calculate the square's area, that is much more simple:

$As= L^{2}$

Where:

$L=20 m$

$As= (20 m)^{2} = 400m^{2}$

To know the whole figure's area, we add up both areas:

$A = At+As = 570m^{2} +400m^{2}=970m^{2}$
