The perimeter for a rectangle (garden) is 2L + 2W.
We have our width, 6.
Plug 6 in for W.
2L + 2(6) = 28
2L + 12 = 28
Subtract 12 from both sides
12 - 12 = 0
28 - 12 = 16.
We're now left with:
2L = 16
Divide both sides by 2 to solve for L.
2L / 2 = L
16 / 2 = 8.
L = 8 (The length is 8).
Now that we have our length, let's solve for the area.
The area of a rectangle is L x W.
8 x 6 = 48.
The area is 48 ft^2.
I hope this helps!
