Answer:
Step-by-step explanation:
Given
per section
Required
Determine the length of the ladder
The length of the ladder is calculated by multiplying the number of sections by the length of each section.
So, we have:
Hence, the length of the ladder is: or 2.25m
Literal equation:
we know that
literal equation is equation of more one variable
for example:
And we can solve such equations only if we are given two such equation
because it has two variables
One variable equation:
such equation has single variables
for example:
we don't need any other equation
we can solve for variables from single equation itself
because it has only one variable that is x
