The area of a rectangular deck is 680 square feet. the deck’s width is 17 feet. what is its perimeter?

Start by finding the length of the deck.

Area of a rectangle is given by A=length*width.

Let's plug in the information that we know so far,

680 = length*17

solving for length, dividing by 17,

40 = length

Now that we know both dimensions of the rectangular deck,
let's calculate the perimeter,

P = 2length + 2width

P = 2(40) + 2(17)

P = 114

Hope that helps!
