Perimeter = side + side + side
= 5/2 + 3 3/5 + 2 3/4
= 5/2 + 18/5 + 11/4
Now, LCM of the denominators
which are 2,5 and 4 = 20
So 5/2 X 10/10 = 50/20
18/5 X 4/4 = 72/20
11/4 X 5/5 = 55/20
As they are now like terms, we can add them easily
50/20 + 72/20 + 55/20 = 177/20 = 8 17/20
Therefore , the perimeter is 8 17/20
= 5/2 + 3 3/5 + 2 3/4
= 5/2 + 18/5 + 11/4
Now, LCM of the denominators
which are 2,5 and 4 = 20
So 5/2 X 10/10 = 50/20
18/5 X 4/4 = 72/20
11/4 X 5/5 = 55/20
As they are now like terms, we can add them easily
50/20 + 72/20 + 55/20 = 177/20 = 8 17/20
Therefore , the perimeter is 8 17/20
