To find: the length of the longest side of
Answer to Problem 13P
The length of the longest side of the triangle is
Explanation of Solution
Given information: “The lengths of the sides of a triangle are consecutive even integers”, “The length of the longest side if it is 22 units shorter than the perimeter”
Concept Involved:
Perimeter of triangle means sum of all the sides of the triangle.
Assign variable for the unknown that we need to find.
Use the keywords in the statement to rewrite the statement to meaningful math equation.
“is” means =
“shorter than” means -
Solve the equation by getting the variable in one side of the equation and undoing whatever is done to it by performing reverse operation.
Calculation: Assign variable for the unknown that we need to find
The three sides of the triangle given that they are consecutive even integer can be represented by
Rewrite the sentence using the variable representing largest side and perimeter
Replace the keywords to get an equation representing the sentence given
Combine like terms in right side of the equation
In the process of getting x in one side of the equation subtract 3x on both sides
Combine like terms on both sides
Subtract 4 on both sides of the equation
Combine like terms on both sides of the equation
Divide -2 on both sides of the equation
Simplify fraction on both sides of the equation
Substitute 10 for x in the expression
Conclusion:
The smallest side is 10, middle side is 12 and largest side of the triangle is 14
