4 dimes=4 *10=40 cents
2.25-0.40=1.85
1.85=0.05 times number of nickles
times 100 both sides
185=5 times number of nickels
divide both sides by 5
37=number of nickles
has 37 nickles
The formula for the area of a square is A=s*s or A=s^2
So we can plug in the area and solve for the side
576=s^2 (square root both sides)
s=24 inches
Since one foot is 12 inches, 24 inches would be 2 feet
Hope this helps
