Question

Jane paints the borders of a tablecloth which is 3 feet long and 2 feet wide. The width of the border on all sides is 5 inches. Find the area of the border which is painted.

• A. 500 square feet
• B. 550 square feet
• C. 600 square feet
• D. 650 square feet

Answer 1

The correct option is A 500 square feet

Area of the tablecloth
= Length × Width

1 feet = 12 inches
3 feet = $3\times 12$ = 36 inches
2 feet = $2\times 12$ = 24 inches

Area of the tablecloth
= $36\times 24$
= 864 square inches

Length of the tablecloth without the border = 3 feet - 10 inches

1 feet = 12 inches
3 feet = $3\times 12$ = 36 inches

3 feet - 20 inches
= 36 inches - 10 inches
= 26 inches

Width of the tablecloth without the border = 2 feet - 10 inches

2 feet = 24 inches

24 inches - 10 inches = 14 inches

Area of the tablecloth without the border = $26\times 14$ = 364 square inches

Area of the border
= Area of the table cloth - Area of the table cloth without the border
= 864 - 364
= 500 square inches
