Answer:

15 inches

Step-by-step explanation:

Call the original side length x

This makes the new length x+5

The perimeter is the sum of the length of the sides. So for the new shape this is 3(x+5)=60

This can be solved in the following way:

x+5=20

x=15

So the original side lengths were 15 inches.

<span><span /><span>The answer to that problem is 813. When you are given a problem like this, you can answer it by using the MDAS technique. MDAS stands for multiplication, division, addition, and subtraction. Since you are following the MDAS technique, you are asked to answer the equation based on MDAS order. To put this simply, look at the example below:

     20x40+3x9/3+4
     800+3x9/3+4
     800+27/3+4
     800+9+4
     809+4
     813</span></span>  

You can clearly see the MDAS order by following the bold text.
