The length of the longer side is 45 units.
What is the length of the longer side?
The perimeter of a rectangle is the distance round a rectangle. It is the sum of the length of the rectangle.
Perimeter of the rectangle = 2(length + width)
146 = 2(length + width)
(length + width) = 146/2
(length + width) = 73
3x + 3 + 2x = 73
5x + 3 = 73
5x = 73 - 3
5x = 70
x = 14
Length of the longer side = 3 + 3(14) = 45 units
