What is the length of the diagonal of square with perimeter 12 m? express the answer as a simplified square root.

Step-by-step explanation:

The perimeter of a square is:

Where "s" is the lenght of a side of the square.

Then, if the perimeter of this square is 12 m, you can solve for "s" and find its value:

You can calculate the length of the diagonal with this formual:

Where "s" is the lenght of a side of the square.

Substituting the value of "s" into the formula  , you get that the lenght of the diagonal of this square is:

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
