Answer:
i hope it will help you...
Step-by-step explanation:
let one side of a triangle be x
then the corresponding side of this new triangle is 2x because it is doubled
sides of new triangle and given triangle are in proportion
∴given triangle is similar to new triangle
new triangle and the given triangle are similar triangles.
by using area of similar triangles theorem,
area of new triangle/area of given triangle=(2x/x)²
=4x²/x²
=4:1
∴ratio of area of new triangle and the given triangle=4:1
plz mark as brainliest...........

_________________________________________
Let the sides of Triangle a,b,c
==> Semiperimeter of Triangle (s)
==>Area Of Triangle :-
Sides Of New Triangle ==> 2a ,2b ,2c.
✴Semiperimeter of Triangle =
Area Of New =>
= 4 × Area Of Triangle
Hence, the area of the new triangle becomes 4 times the area of the original triangle.
So Ration => 4:1
