Answer:
We can represent a number in general by x . Halving a number means dividing it by two, so the expression that shows the half of a number is x2 , since you divide a number by two.
Step-by-step explanation:
To find the actual area or perimeter, you need to make the centimeters into meters. But, you have to use the scale. ( 1cm : 320m )
L=13.5
You need to multiply 13.5 and 320 (because that's how much more there is in the other model or the meter's shape)
13.5 * 320 = 4,320.
The actual Length in meters is 4,320.
Do the same with W.
3.3 * 320 = 1,056.
<span>Now you have the real lengths.
</span><span>Area = L * W
</span>So you put in the real measurements.
Area = 4,320 * 1,056
Area = 4,561,920.
Perimeter is the sum of all sides, so Sum up all of the sides' measurements.

Mutiply them all out, you'll get quadratic equations. Replace x's with numbers and then you'll be able to draw the graphs
All parallel lines have the same slope. So the product of the slopes of line AB n a line parallel to AB is m*m=m^2
