| a | b | h | |
|---|---|---|---|
| 1) | 9 | 16 | \[ \sqrt{9 \cdot 16} = \sqrt{144} = 12 \] |
| 2) | 25 | 9 | \[ \sqrt{25 \cdot 9} = \sqrt{225} = 15 \] |
| 3) | \[ \sqrt{36^2 + 12^2} = \sqrt{1296 + 144} = \sqrt{1440} = 12\sqrt{10} \] | 36 | 12 |
| 4) | 25 | \[ \sqrt{21^2 + 25^2} = \sqrt{441 + 625} = \sqrt{1066} \] | 21 |
| 5) | \[ \sqrt{9^2 + 21^2} = \sqrt{81 + 441} = \sqrt{522} = 3\sqrt{58} \] | 9 | 21 |
| 6) | 1 | \[ \sqrt{16^2 + 1^2} = \sqrt{256 + 1} = \sqrt{257} \] | 16 |
| 7) | \[ \sqrt{1+7^2} = \sqrt{1+49} = \sqrt{50} = 5\sqrt{2} \] | 7 | |
| 8) | 4 | \[ \sqrt{4^2 + 3^2} = \sqrt{16+9} = \sqrt{25} = 5 \] | 3 |
| 9) | 5 | \[ \sqrt{5^2 + 9^2} = \sqrt{25+81} = \sqrt{106} \] | 9 |
| 10) | \[ \sqrt{4+2^2} = \sqrt{4+4} = \sqrt{8} = 2\sqrt{2} \] | 4 | 2 |
