Long side of rectangle: 3x+3
short side: 2x
the perimeter of the rectangle is 146 units. what is the length of the longer side?

The answer is:

The length of the longer side of the rectangle is equal to 45 units.

To solve the problem, we need to use the formula to calculate the perimeter of a rectangle, then, isolate the variable and finally, calculate the length of the longer side.

We can calculate the perimeter of a rectangle using the following equation:

Let be the length the longer side and the width the short side of the rectangle.

Then, substituting the given information and calculating we have:

Now, calculating the long side of the rectangle, we have:

Hence, we have that the length of the longer side of the rectangle is equal to 45 units.

Have a nice day!
