Let x be the original side length of the square
P=2(l+w)
70=2((2.5+x)+(2.5+x))
70=2(5+2x)
70/2 = 5+2x
35-5=2x
30=2x
15=x
Therefore, the original length of the square was 15"
Hope I helped :)
I can’t help and also it would be too late so sorry also I’m doing this to ask a question sorry again

Answer:
1/5 and 3/15
Step-by-step explanation:
12/60 reduces to 1/5 if we divide numerator and denominator by 12.
Thus, 12/60 = 1/5.
If we now multiply both numerator and denominator by 3, we get 3/15, which is identical to 1/5.
Thus, the two fractions in question are 1/5 and 3/15.
