Question

Mara wants to use tiles to cover the bottom of a rectangular box that measures 24 inches long by 2 inches wide.

She has 20 small square tiles with side lengths of 1 inch and 10 large square tiles with side lengths of 2 inches.

If Mara uses all the small tiles first, how many large tiles will she need to use?

Answer 1

The answer is 4 books

Answer 2

to get the answer you would have to find the area of the rectangular box and then multiply the 20 1 inch tiles and get the coverage of those tiles and then you would have to subtract that number by the area of the box and then find out how many 2 inch tiles Mara will need
