length of string B = 64 centimeters.
step 1
we solve for the Highest common denominator between them.
highest common denominator = 16.
what this represents is that no string would be cut more than 16inches so they can all have equal lengths at the end of cutting.
A^2 + b^2 = c^2 a=4 b= 6
4^2 + 6^2 =52
square root that:
c=2 square root 13 exactly or 7.2 approximately <span />
