<u><em>Question 10.</em></u>

Length of the side of the square = \sqrt{441} = 21

By Pythagoras' Theorem,

Hypotenuse = \sqrt{21^{2} + 20^{2} } (H > 0)

                     = 29 m

Ans: 29 m

<u><em>Question 11.</em></u>

By Pythagoras' Theorem,

Length of longer side of 42 km = 42- \sqrt{18^{2} - 15^{2} } (L > 0)

                                                                     = 32.050 km (5 s.f.)

By Pythagoras' Theorem,

Length of the unknown side = \sqrt{32.050^{2} + 15^{2}  } (L > 0)

                                               = 35.4 km (3 s.f.)
