The length of a rectangular garden is 3 meters less than twice the width. . Find the width and the length of the garden.
length(L);
width (W);
***You are told that:
The length of a rectangular garden is 3 meters less than twice the width
In math terms this means
L = 2W -3
***Also:
That three times the width of the garden equals two time the length
3W = 2L
**You are asked to find the length and the width:
The easiest way to solve this is to put everything together in terms of jusy one variable.
if you pick:
3W = 2L ---> Substitute L by 2W -3
3W = 2 (2W-3)---> You have an equation in terms of one variable, in this case, the width.
if you solve for the variable:
3W= 4W-6
-W = -6
W = 6
Now, you know what the width is, the last thing you have to do is to plug it back in the first equation to find the length.
L = 2W - 3
L = 2(6) - 3
L = 12 - 3
L = 9
So, you found that the length is 9 units and the width is 6 units.
hope it helps~!
