As this is a right angle triangle.

using trigonometric identity:

tanA= Perpendicular/Base

In the given figure :

Perpendicular P= √5

Base B =O

so, Tan 30°= P/B

  1/√3 = √5/

doing cross multiplication we have:

 O= √5×√3

 O=√15

To find value of Hypotenuse, we will trigonometric identity:

Cos 30°= Base/ Hypotenuse

 √3/2 = √15/p

doing cross multiplication we get:

√3×p = √15×2

p = (√15 × 2)/ √3

p= (√5 × √3 × 2)/√3

p= 2√5

Hence, the Base is √15 and Hypotenuse p is 2√5.
