A table top is rectangular. The table’s length is 60cm more than its width. The perimeter of the table is 240cm. Find the width of the table top.

Answer 1

P=240 L=60+w

240 = 2L +2w

120 = L +w = 60+w+w = 60 +2w

60 = 30 +w

w = 60-30=30 cm wide

L= 90 cm Long

width = 30 cm = .3 meters = 30/2.54 = 1500/127= about 11.811 inches = about 1 foot wide
