Answer:
The length of EF = x = 18 cm
Option A is correct.
Step-by-step explanation:
Ware given perimeter of triangle = 97 cm
We need to find length of EF = x = ?
The length of EG = x+7
The length of EF = x
The length of GF = 3x
The formula used is: ![Periemter \ of \ triangle= Sum \ of \ all \ sides \ of \ triangle](https://tex.z-dn.net/?f=Periemter%20%5C%20of%20%5C%20triangle%3D%20Sum%20%5C%20of%20%5C%20all%20%5C%20sides%20%5C%20of%20%5C%20triangle)
Putting values and finding x i.e length of EF
![Periemter \ of \ triangle= Sum \ of \ all \ sides \ of \ triangle\\97=x+7+x+3x\\97-7=5x\\5x=90\\x=\frac{90}{5}\\x=18 \ cm](https://tex.z-dn.net/?f=Periemter%20%5C%20of%20%5C%20triangle%3D%20Sum%20%5C%20of%20%5C%20all%20%5C%20sides%20%5C%20of%20%5C%20triangle%5C%5C97%3Dx%2B7%2Bx%2B3x%5C%5C97-7%3D5x%5C%5C5x%3D90%5C%5Cx%3D%5Cfrac%7B90%7D%7B5%7D%5C%5Cx%3D18%20%5C%20cm)
So, value of x=18 cm
The length of EF = x = 18 cm
Option A is correct.

Step-by-step explanation:
Answer:
72
Step-by-step explanation:
because if you add 18, 4 times or 18 x 4 it will give your 72
hope this helps
First we will change them on the same denominator which will be 12. If we do something to the denominator we must do the same to the numerator so :
For 1/3 we get 4/12 because (1/3)*4 = 4/12
And for 2/3 we get 8/12 because (2/3)*4 = 8/12
So 1/3 is the smaller fraction, 7/12 is in the middle and 2/3 is the bigger fraction.
