Question

Tanya plans to make a square deck. She is not sure what size she is going to make the deck, but she knows it needs to be more than 5 feet long. She represents the deck as a square in which each side is d+5 feet long. Write an expression for the perimeter by multiplying the number of sides by the length of a side.

Answer 1

To express the perimeter of Tanya's square deck, we multiply the number of sides (4) by the length of a side (d+5).

Step-by-step explanation:

To write an expression for the perimeter of Tanya's square deck, we need to find the length of one side of the deck and then multiply it by the number of sides. The problem states that each side of the deck is d+5 feet long. So, the length of a side of the deck is d+5 feet. Since a square has 4 sides, the perimeter of the deck can be expressed as 4(d+5).
