Answer 1

Answer:

Question 10.

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

Question 11.

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.)

Ans: 35 km
