<human>:  Bob is building a garden on his land, and he wants it to be fenced in to keep out varmints. The garden is a rectangular plot 225 feet long by 125 feet wide. He also wants to have a small 3-foot wide gate to walk through and a larger 10-foot wide gate to move his gardening equipment through. How much fencing is Bob going to need to fence in his garden, taking into account the two gates?
<bot>: How many feet is the perimeter of the garden? ** The perimeter of the garden is 2 * 225 + 2 * 125 = 450 + 250 = <<2*225+2*125=700>>700 feet.
How many feet of fencing does Bob need? ** Minus the two gates, he will need at least 700 - 3 - 10 = <<687=687>>687 feet of fencing.
