Question 193186
I looked at the solution for question #193175:
A diagonal walk through a rectangular rose garden 18 meters by 24 meters can be built at $12 per linear meter. How much will the walk cost? 
But I was unable to figure out what ankor was talking about. I am not as versed in using a calculator as some are and did not understand. Can someone help please. 
-----------------
Find d, the length of the diagonal.  The sides are 18 m and 24 m.
d^2 = 18^2 + 24^2 (Pythagoras' Theorem)
d^2 = 324 + 576 = 900
d = 30 meters
-------------
30 m times $12/meter = $360
