Question

Which expression represents the perimeter of the rectangle above? . 6x + 3. 10x + 6. 8x² + 6x. 12x + 6

Answer 1

The perimeter of a rectangle is the sum of its four sides. Because a rectangle, by definition, has two pairs of similar sides, you simply multiply the given dimensions by two: (4x + 3) + (2x + 2x) + (2x + 2x) + (2x + 2x) + (2x + 2x) + (2x + 2x) + (2x Then, group related terms together: 12 times + 6

Answer 2

The perimeter of a rectangle will be all four sides added together. Since a rectangle, by definition, has two pairs of similar sides, you will simply add the given dimensions twice each: (4x + 3) + (4x + 3) + 2x + 2x. Then, add together like terms: 12x + 6
