The length and width for a maximum area is 10 popsicle by 10 popsicle.
What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables. An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.
Let x represent the length to Craig's house and y represent the width. Hence:
2(x + y) = 40
x + y = 20
y = 20 - x (1)
Area (A) = xy = x(20 - x)
A = 20x - x²
The maximum area is at A' = 0, hence:
A' = 20 - 2x
20 - 2x = 0
x = 10
y = 20 - (10) = 10
The length and width for a maximum area is 10 popsicle by 10 popsicle.
