Triangle perimeter: ( 3 \times 8 = 24 ) Square perimeter: ( 4s = 24 ) → ( s = 6 ) Area of square: ( 6^2 = 36 )

For ( 5a4 ) divisible by 9: sum of digits must be multiple of 9. Digits: ( 5 + a + 4 = 9 + a ) must be divisible by 9 → ( 9+a = 9 ) or ( 18 ). So ( a = 0 ) or ( a = 9 ).

If ( a=0, b=7 ) → ( a+b = 7 ) If ( a=9, b=7 ) → ( a+b = 16 ) (larger) Smallest = 7. Mathcounts National Sprint Round Problems And Solutions
