The two equal sides in an isosceles triangle must be shorter than the third side, by definition.
All you need to do is add up the two shorter sides, then add the third longer side to see which total adds up to 52, since the perimeter of a triangle is just the sum of its three sides:
A. 15+15+25=55
B. 15+15+22=52
C. 12+12+22=46
D. 16+16+21=53
The answer is therefore B, since the sum of the three sides is 52 inches.
I hope this helps!
