Answer provided by our tutors
Let
l = the length of the table, l>0
w = the width of the table, w>0
A = 72 m^2 the area of the table
The length of the top of a table is 6 m greater than the width:
l = w + 6
The area of the rectangular table is:
A = l*w
l*w = 72
Plug l = w + 6 into the last equation:
(w + 6)*w = 72
........
........
w = 6 m
l = 6 + 6
l = 12 m
The dimensions of the table are: the length is 12 meters and the width is 5 meters.
