So, there are 1, 5, 10, 25 and 50 cent coins.
The most logical combination would be a dime and a quarter (10 + 25 = 35) but it is said that "one of the coins is not a dime".
But, there is something many people don't notice. It says that one of the coins isn't a dime, but the other one can be a dime. So, the two coins are a quarter and a dime.
Hope it helped,

48" means 48 inches
anyway
the perimiter is the distance around or the sum of the sides
perimiter=48=x+3+4x-1+2x-3=7x-1
48=7x-1
add 1 to both sides
49=7x
divide both sides by 7
7=x
x+3=7+3=10
4x-1=4(7)-1=28-1=27
2x-3=2(7)-3=14-3=11
the sides are 10", 27" and 11"
x=7
