Split the shape into smaller regular shapes. Calculate the area of those then add it up.

triangle on left, base = 3 height = 8
area = 0.5(3)(8)
= 12

middle rectangle, width = 6 height = 8
area = 6(8)
= 48
 
small rectangle width = 2 height = 6
are = 6(2)
=12

two tiny triangles become a square side = 2
area = 2(2)
= 4

add them all up...

Total area = 12 + 48 + 12 + 4
= 76 units²

Is ab perpendicular to cd ? Explain.
Afina-wow [57]
We know that
if two lines are perpendicular
then
the slopes 
m1*m2=-1

step 1
find the slope AB
A (0,2)
B (-3,-3)
m=(y2-y1)/(x2-x1)-----> m=(-3-2)/(-3-0)-----> m=-5/-3----> m1=5/3

step 2
find the slope CD
C (-4,1)
D (0,-2)
m=(y2-y1)/(x2-x1)-----> m=(-2-1)/(0+4)-----> m=--3/4----> m2=-3/4

step 3
multiply mi*m2
(5/3)*(-3/4)-----> -15/12
so
15/12 is not -1
therefore
 AB is not perpendicular to CD

4b.) Write an equation using point-slope form with a slope of 2.3 and goes
Yuri [45]

Answer:

y+3.2=2.3(x-4.5)

Step-by-step explanation:

So the point-slope formula looks like this: y-y_1=m(x-x_1)

y_1 = any y point on the line

x_1 = any x point on the line

m = the slope

And hey, look, we're already given all that information!

So we can just plug those values into the equation:

y+3.2=2.3(x-4.5)

(*note: It's a +3.2 because 3.2 was negative in the first place, and -(-x) = +x)
