Question
If all three dimensions of a triangle are doubled, then which of the following statements about
its perimeter will be true? 4:1, 1:2, 2:1, 3:1. If anybody knows this please respond asap
Answer:
1 : 2
Step-by-step explanation:
First situation
sides of triangle:-
a=x, b=2x, c=3x
then perimeter = a+b+c
perimeter = x + 2x + 3x
Perimeter = 6x
Second situation(sides are doubled)
sides of triangle:-
a=2x, b=4x, c=6x
then perimeter = a+b+c
perimeter = 2x + 4x + 6x
Perimeter = 12x
Ratio of first situation to second
Perimeter of first situation : Perimeter of second situation
6x : 12x
1 : 2
