Answer:
For a trapezium of height H, parallel side 1 X, and parallel side 2 Y, the area is:
A = (1/2)*H*(X + Y)
with this we can complete the table.
a)
Here we know:
X = 7cm
Y = 11cm
H = 6cm
Then: A = (1/2)*6cm*(7cm + 11cm) = 54 cm^2
b)
Here we know:
X = 8 m
Y = 10 m
A = 126 m^2
Then:
126 m^2 = 0.5*H*(8m + 10m)
126 m^2 = H*9m
126 m^2/9m = H = 14m
Then the height of this trapezoid is 14m
c)
Here we know:
X = 5mm
H = 8mm
A = 72 mm^2
Then:
72 mm^2 = 0.5*8mm*(5mm + Y)
72 mm^2 = 4mm*(5mm + Y)
72mm^2/4mm = 5mm + Y
18 mm = 5mm + Y
18mm - 5mm = Y
13 mm = Y
Then the parallel side 2 is 13 mm long.

Step-by-step explanation:
The independent variable is the cause - the Scary Movie
The dependent variable is the effect. Its value depends on changes in the independent variable, so the dependent variable is the number of flinches.
The rectangular room is 10.25 inches by 8 inches. If 1 inch represents 2 feet of the actual room. What is the scale factor and actual area of the room?
10.25 x 2 = 20.5 ft
and
8 x 2 = 16 ft
1in/ 2 ft or 1 in/ 24 inches
