Why do you have to use estimation to find the number of triangles you need for the string?
{could you please me I don't understand
Estimation is used when you need to make an approximate calculation or find a rough value without exact measurements or detailed information. In the context of finding the number of triangles you need for a string, estimation can be helpful because it allows you to make an educated guess or approximation instead of carrying out an exact count.
To explain further, let's consider an example where you want to decorate a string with triangular flags. If you have a large number of flags to hang, it would be time-consuming and tedious to count each individual flag one by one. Here's where estimation comes into play.
To estimate the number of triangles needed for the string, you can use a representative sample of flags. Take a small section of the string and count the number of flags in that portion. Then, measure the length of the string covered by that sample section. By multiplying the ratio of the length of the entire string to the length of the sample section by the number of flags in the sample section, you can estimate the total number of flags needed for the entire string.
Estimation saves time and effort, allowing you to get a reasonably accurate answer without performing an exhaustive count. It is especially useful when dealing with large numbers or situations where exact measurements or counts are not possible or practical.
