1 ha = 100 by 100 meters 9 ha = 100 by 100 times 9 = 90 000 metres squared
9 Squared is 81.Squared means to times a number by itself so..... 9 squared = 9x9 = 81!
10 sq is 100 9 sq is 81 100-81 is 19
109 = 9 + 100
1 squared = 1 2 squared = 4 3 squared = 9 4 squared = 16 5 squared = 25 6 squared = 36 7 squared = 49 8 squared = 64 9 squared = 81 10 squared = 100
9
If you mean (2 times 5) squared then it is 100
9 x 9 = 81 9 squared = 81 3 squared times 3 squared = 81
3 squared is the same as saying 3 times itself which = 9. The answer to 3 squared is solved using these steps. Squared = to the second power Which is to multiply the number by its self 2 times. So 3 squared is 3 times three. So your answer is 9
9 plus 16=25 3 squared is the same as 3 times three and 4 squared is the same as 4 times 4 3 times 3 + 4 times 4 9 plus 16 = 25
100. the pattern is 7 squared, 8 squared, 9 squared....
x times the sum of x and 9 x times (x times 9) x(9x) 9 times x[squared] 9x[squared]
