**CHALLENGE** A small table is 2 feet by 3 feet. A large table is twice as long and twice as wide as the small table. What is the area of the large table in square feet?

Answer:

Given that,

The length of the small table is 2ft.

The breath of the small table is 3ft.

The area of the rectangle is length x breath.

length of the large table is 2 x 2 = 4ft.

Breath of the large table is 3 x 2 = 6ft.

Therefore the area of the large table is 4 x 6 = 24sq.ft.

Therefore the area of the large table is 24 square feet.
