Answer:
45 units
Step-by-step explanation:
The perimeter is equal to 2(width+length)
Let the longer side be the length of the rectangle
2(2x+3x+3)=146
Divide both sides by 2
2x+3x+3=73
5x+3=73
5x=70
x=14
The longer side = 3x+3
substitdude x into the equation
3(14)+3
= 45 units
There are total 17bills of $20 dollars and 6 for $10 bills.
We get the answer of $20 bills by dividing 340 and 20 then we get 17 then subtract the value from total bills than you get 6 bills for $10 dollars
