A glass tabletop is supported by a rectangular pedestal. if the tabletop is 8 inches wider than the pedestal on each side, what is the perimeter of the glass tabletop

When adding make sure you add 4 sides worth of calculations. You have to consider the left and right side (for length) and front and back for the width.

The solution for this problem is:

Side 1 (8+36+8)

+

Side 2 (8+48+8)

+

Side 3 (8+36+8)

+

Side 4 (8+48+8)

= 232
