To help you figure out the length and width.
00:04
We know that the length of the garden is equal to 5 plus the width.
00:12
In this case, we know the area as well, and the area of a rectangle is linked.
00:20
Knowing this, we can use substitution and have one variable in our equation.
00:25
We're given that the area of the garden is 300.
00:28
So 300 equals w plus 5 times w.
00:37
Here we can use our spoiling and we multiply times each one.
00:44
We get 300 equals w squared plus 5w.
00:50
In order to factor, we want to set this equal to zero.
00:53
So we need to move the 300 over and we get 0 equals w squared plus 5 w minus 300.
01:06
To factor this, we need to know our factors of 300.
01:09
Sometimes it helps to draw well factor true.
01:12
You know your factors of 30, so you can make those times 10...
