A table is 9 feet long and has a perimeter of 24 feet. What is the area of the top of the table?

Answer 1

Area is Length times width.

Perimeter is 2L+2W

Replace L with the given length of 9 and solve for the width.

2(9)+2w=24

18+2w=24. subtract 18 from both sides

2w=6. divide both sides by 2

w=3

Now we know the length and width so L times W would be 9x3=27 which is the area.
