Aneli [31]

diagonal = sqrt(l^ + w^2)

17 = sqrt(10^2 + x^2)

17^2 = 10^2 + x^2

289 = 100 + x^2

189 = x^2

x = sqrt(189) = 13.747

X = 13.75

3. The \sqrt{18} is between 4 and 5.

2. \sqrt{54}: 10 is near the perfect squares 49 and 64, which would mean its answer is between their square roots which are 7 and 8.

3. \sqrt{18}: 10 is near the perfect squares 16 and 25, which would mean its answer is between their square roots which are 4 and 5.

4. \sqrt{99}: 10 is near the perfect squares 81 and 100, which would mean its answer is between their square roots which are 9 and 10.
