One thing to mention is that area is equal to length times width for a rectangle.
00:06
I use a cursive l because otherwise it will look like a 1.
00:10
So let's go ahead and give a visual for you where you have a width and they tell you that the length is 200 more, so 200 plus twice the width.
00:23
That means 2w and that's what we'll have equal l.
00:27
So in my formula up here, i may replace l with 200 plus 2w.
00:34
W is still w.
00:36
And they tell you the problem that the area is 40 ,000 square yards.
00:42
I'll just go ahead and put yards squared just so we know our final unit.
00:49
So anyway, what you'd want to do is distribute the w in there.
00:52
So 200w and distributing you get 2w squared.
00:57
At the same time, i'm going to go ahead and subtract that 40 ,000 to the left side so i can get it equal to zero...
