Martha's bathroom is shaped like a rectangle with dimensions of 5ft by 7ft. The floor of the room is made of decorative square tiles with a side length of 1/4 ft. What is the number of decorative tiles Martha will need to purchase?

you multiply 5 ft by 7 ft which gives you 35 ft. and since the tiles are within the rectangles all you need to do is multiply by 4. The answer is 140 ft
