The parameter of a rectangle can be alculated using the following rule:
parameter = 2(length + width)
from the givens:
length = 13 inches
width = 10 inches
so, just substitute with the givens in the equation to calculate the parameter:
parameter = 2(10+13) = 2*23 = 46 inches
Answer:
The third equation:
Step-by-step explanation:
The two points on the line are and .
Slope of the line passing through two points and is given as:
Here, and are and .
Therefore, slope is equal to,
Now, equation of a straight line with slope m and points and is given as:
Now, if we use the 2nd form, then .
So, the equation is given as :
