Step-by-step explanation:
Answer:
5/2
Step-by-step explanation:
The scale factor for linear measures, such as perimeter, is the square root of the scale factor for areas. The ratio of larger area to smaller is ...
... 75/12 = 25/4
so the ratio of the larger perimeter to the smaller is ...
... √(25/4) = 5/2
4x + y = 54
8x + 2y = 104
8x + 8y - (8x + 2y) = 240 - 104
6y = 136
y=22 2/3
4x+ 22 2/3 = 54
4x= 31 1/3
x= 7 5/6
Multiply the 2nd equation by -3 to get -3x-12y = -48.
We know that an equilateral triangle has all sides equal.
Initial perimeter = s + s + s = s
Each side has been increases by then the new perimeter is:
(s+15) + (s+15) + (s+15) = 3s + 45
So the new perimeter = 3s + 45
