All About Perimeter

Dinah C. Quiros
The Smith family lives in Rochester, New York. They love the environment outside the big city because they all love to spend most of their free time around their 20 acres land.
Louise loves to spend her summer landscaping their yard. Her flower garden is formed like a triangle with the sides 3x + 5, 6x - 7 and 5x + 2. What is the perimeter of Louise's flower garden?
Nick, Louise's younger brother, is also fond of gardening. He has a rectangular vegetable garden. He wants to put a fence around it. If Nick's garden has a width of 4x - 3 and a length of 12x + 4, what is the perimeter of his vegetable garden?
Early each morning, Louise walks her pet dog around a regular hexagon walkway.
The walkway has six lamp posts with a distance 10x + 2 from each other. What is the perimeter of the hexagonal walkway?
On the other hand, Nick loves to jog around the park near their house. The park is in the form of a regular hexagon. If the length of one side is represented by the expression 12x + 4, what is the perimeter of the park? After each round, he used to cross the park through the center forming a diagonal whose length is represented by the expression 15x - 2, what is the perimeter of the half of the hexagonal park?
