Difference of legs

In a right triangle, the length of the hypotenuse is 65 m, and the difference of legs is 23 m. Calculate the perimeter of this triangle.

Correct result:

o =  154 m

Solution:

c=65 m a=b+23 c2=a2+b2  652=(b+23)2+b2  652=(b+23)2+b2  652=(33+23)2+332  b>0 b=b1=33=33 m a=b+23=33+23=56 m  o=a+b+c=56+33+65=154 m
