Cho is making a rectangular garden, where the length is x feet and the width is 2x + 1 feet. he wants to add garden stones around the perimeter of the garden once he is done. if the garden is 6 feet long, how many feet will cho need to cover with garden stones? cho will need to feet with garden stones.

The length of the garden 6 feet. Because the length is also represented by 'x', we can say that x = 6. Then, we can substitute 6 in for x in the width's equation and simplify into 13 feet. Finally, we can plug those numbers into the equation to find the perimeter of a rectangle and simplify.

x = 6
2(6) + 1 = w (width)
12 + 1 = w
13 = w           &          6 = l (length)

2(l) + 2(w) = p (perimeter)
2(6) + 2(13) = p
12 + 26 = p
38 = p

Cho will need to cover 38 feet with garden stones.

Hope this helps!

6(2x + 5y)6 (2x) = 12x6 (5y) = 30y12x + 30y

If you divide 0.1 and 0.6 you wii get 0.166666 which rounds to .167 which is answer b
