The length of the legs of an isosceles triangle is 6 meters more than its base. If the Perimeter of the triangle is 66 meters, find the lengths of the sides of the triangle.
Help me out with this question.
Please read Read Before Posting.
Before doing anything else, ask yourself whether you can draw a quick sketch so you can see what you are thinking about. This step is not always possible, but ask yourself whether it is. If it is draw that sketch.
The next thing to do in
ANY word problem is to assign,
in writing, letters to the relevant variables. You do it in writing so you do not have to keep it in memory while you are trying to think and so you can communicate about your problem if necessary.
OK The question is about the lengths of the sides of an isosceles triangle. There are three sides so there are three variables.
a = length of leg A.
b = length of base B.
c = length of leg C.
The next thing to do is to write down what you know about your variables in mathematical language using the letters assigned. Some of this information comes from the problem itself and some comes from general knowledge. If you have n variables, you need n pieces of information to solve the problem. You have three variables so you are looking for three pieces of information.
Here is one from the problem itself
a + b + c = 66.
You need two more. Why did tkhunny ask you about how to define an isosceles triangle?
