Answer:
1:2
Explanation:
Initially, the base and height of a right angle triangle is 12 and 5.
The hypotenuse can be calculated using Pythagoras theorem such that,

When sides are doubled,
Base = 24
Height = 10
Hypotenuse = 26
Perimeter of the triangle = 24+10+26 = 60
The area of riangle,

Required ration,
