Your original answer was correct...
Both polygons have five sides, and five sided polygons are called pentagons.
5^2 = a^2 + b^2
25 = a^2 + b^2
the other sides need to be shorter than 5 so plug them and and see what works:
25 = 4^2 +4^2 = 25 = 16+16 = 25 = 32 false
25 = 4^2 + 3^2 = 16+9 = 25, 25 = 25 True
the only one that works would be sides of 3 and 4 units long
