four square tables are arranged next to each other to form one large rectangular table.the perimeter of the large rectangular table is 20m.what is the perimeter and area nof each square table?

Hmmm. If it says rectangular, rather than square, the small tables must have been arranged in a line. SO, if the side of each table is x, then the line of 4 has
length=4x
width=x
perimeter=10x, so x=2
There are four 2x2 tables in a line.
small tables have area 4, perimeter 8.
Now, if the 4 tables are arranged in a square, then the large square has side 2x, perimeter 8x, and x = 2.5 
12m
