Xiao Hong's family has a round dining table with a diameter of 1.2 meters and 2 meters. Her mother bought a square tablecloth and spread it on the table
Xiaohong's family has a round dining table with a diameter of 1.2 meters and 2 meters. Her mother bought a square tablecloth and spread it on the table. The four corners of the tablecloth just touch the ground. How many square meters is the area of this tablecloth?

It should be 6.48
But I know the diagonal length of a square is 1.2 + 1.2 + 1.2
The area should be 0.5 times the square of 3.6

A table is 1 meter long and 60 cm wide. A cloth should be laid on the table to make it all around

I'm not finished with the questions!
I temporarily press to make the tablecloth hang 20 cm around the table?
1m=100cm
The area of the square table is: 100 x 60 = 6000 CM & # 178;
The hanging part and long side of the tablecloth are: 100 x 20 = 2000 CM & # 178;
The wide side is: 60 x 20 = 1200 CM & # 178;
The whole tablecloth area = 6000 + 2000 x 2 + 1200 x 2 = 12400cm & # 178; = 1.24M & # 178;
