"Ahmed Knots"
Ahmed, an Egyptian farmer is designing his garden near the Nile River. As was the custom in ancient times, he used a rope with equally spaced knots to help him with his measurements. How many full spaces between knots must be on the third side of this triangle so that he knows his field is "squared off" (a right angle)?
I missed this question. Does anyone get it? =/?
A right angled triangle has the ratio 3:4:5...3 up,4 across... the diagonal is 5..
