So in this problem, we're told that we have a lawn that measures 60 by 40.
00:04
So i think it's gonna be helpful to draw this up.
00:06
So i'm assuming it's also a rectangle.
00:08
So here's our lawn, and we know this distance is 60 meters, and this distance is 40 meters.
00:15
Now we're told that there's a 1 meter footpath around it.
00:18
So essentially, almost think that there's a path that's going...
00:21
Oop, could have drawn that a little bit straighter...
00:25
That's going around this.
00:27
And when they say 1 meter distance, that means the distance from here to here is 1 meter.
00:31
This is also 1, this is 1, this is 1, and that's gonna continue the pattern around.
00:39
So this width is equal to 1.
00:41
Okay, our ultimate goal is to find the cost to repair this if it costs $8 per square meter.
00:46
Well, in order to do that, we have to find the area of this entire section on the outside.
00:51
Well, that's not a typical shape that we have...
