9a+12=30
9a=18
a=2
963 would be rounded to become 1000.
This is because 9 is the first non-zero number and so since there are only going to be 1 significant figures, the 9 would round up or down. There is a 6 after the 9, so it rounds up to 10, making it 1000.
Side of the playground would be : a²+a² = 16²
2a² = 256
a² = 128
a = √128
a = 11.31 m
