Perimeter with Polynomials

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2(length + width)

Front

What is the perimeter of a rectangle with length 3x and width 2x?

Back

Perimeter = 2(3x + 2x) = 10x

Front

What is the perimeter of a triangle with sides 3a, 4a, and 5a?

Back

Perimeter = 3a + 4a + 5a = 12a

Front

How do you find the perimeter of a polygon?

Back

Add the lengths of all sides together.

Front

What is the perimeter of a square with side length x?

Back

Perimeter = 4x

Front

If the perimeter of a rectangle is 20 and the length is 6, what is the width?

Back

Width = (20/2) - 6 = 4

Front

What is the perimeter of a rectangle with polynomial dimensions (length = 2x + 3, width = x + 1)?

Back

Perimeter = 2((2x + 3) + (x + 1)) = 6x + 8

Front

What is the perimeter of a triangle with sides represented by polynomials (sides = x + 2, 2x - 1, 3x + 4)?

Back

Perimeter = (x + 2) + (2x - 1) + (3x + 4) = 6x + 5

Front

What is the perimeter of a rectangle with length 5x and width 2x?

Back

Perimeter = 2(5x + 2x) = 14x

Front

What is the perimeter of a triangle with sides 2y, 3y, and 4y?

Back

Perimeter = 2y + 3y + 4y = 9y
