1 ha = 100 by 100 meters 9 ha = 100 by 100 times 9 = 90 000 metres squared
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
When you square a number, you multiply it by itself. So, 9 squared means 9 multiplied by 9, which equals 81. In mathematical notation, 9 squared is written as 9^2 or 9 x 9.
If you mean (2 times 5) squared then it is 100
9
The expression "-9 squared" means to multiply -9 by itself. When you calculate this, you get ((-9) \times (-9) = 81). Therefore, -9 squared equals 81.
To work out 9 squared, you multiply 9 by itself. This means calculating (9 \times 9), which equals 81. Therefore, 9 squared is 81.
11 times 3 squared is equal to 11 times 9, which equals 99.
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
