(Sorry its a little late)
This question asked what the diagnol length of a square (or two triangles right next to each other) was if it had two sides (legs) with the measurments:
With c as the diagnol length.
So to discover the length we use the formula a²+b²+c²
And now we begin the long math equation:
So now we simply write a simple sentince answer
The diagnol length of the rectangle is 13.4m.
Again I apologize for this post being a little late, and remember that tomorrow is the last day of pythagoras and we need 8 of the math books questions done.
