Calculate the perimeter of a square whose diagonal measures 29 dm.

dm

Step-by-step explanation:

A square's diagonal cuts across the square, making two right triangles where the diagonal is the hypotenuse.

We have a right triangle with a hypotenuse of 29, and two legs that are the same length (because they are sides of a square)

So, we can use pythagoreans theorem to find the lengths of the legs, or sides of the square.

Now that we have a side length of , we just have to multiply that by 4, since a square has 4 sides. This leaves us with a final perimeter of:

answer: 230 miles ( vote ! )

step-by-step explanation:

180.39 minus 17.99 equals 162.4

then divide 162.4 by .80 to get 230

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
