The answer is 1988 cm².
The method:
1. First, find the rectangular table area.
We will add the length and the wide of cloth by (7 cm × 2) = 14 cm.
So, we got (78 cm + 14 cm = 92 cm) and (50 cm + 14 cm = 64 cm)
After that, multiply the length and the wide of rectangular table.
Area of table = 92 cm × 64 cm = 5888 cm²
2. Second, find the area of cloth.
Multiply the length and the wide of cloth.
Area of the cloth = 78 cm × 50 cm = 3900 cm²
3. Then, find the area of table not covered by cloth by subtract the area of rectangular table and the area of cloth.
Area = 5888 cm² - 3900 cm² = 1988 cm²
So, the area of table not covered by cloth is 1988 cm².
