18 cm
6 cm
(not drawn to scale)
360 cm
B 6 10 cm
А
144 cm
D 216 cm

Answer 1

B

Explanation:

Using Pythagoras' identity in the right triangle

let h be the hypotenuse, then

h² = 6² + 18² = 36 + 324 = 360 ( take the square root of both sides )

h =
`√(360)`

=
`√(36(10))`

=
`√(36)` ×
`√(10)`

= 6
`√(10)` → B
