The perimeter of the rectangle is 146 units. What is the length of the longer side? 1 side = 2x, 2nd side = 3x+3

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
