A brick wall measuring 3 ft by 11 ft is to be built. The brick measures 4in by 6 in. How many bricks will it take to complete the walkway?
Are we building a wall or a walkway?

To find out how many bricks are needed to complete the brick wall, we need to calculate the total number of bricks that can fit into the given area.
First, let's convert all the measurements to the same unit. Since the measurements of the bricks are given in inches and the area of the wall is given in feet, we need to convert the area of the wall to inches.
The brick wall measures 3 ft by 11 ft:
3 ft = 36 inches (since 1 foot = 12 inches)
11 ft = 132 inches
Now, let's calculate the area of the wall in square inches:
Area of the wall = Length x Width
= 36 inches x 132 inches
= 4752 square inches
Next, let's calculate the area of one brick:
Area of one brick = Length x Width
= 4 inches x 6 inches
= 24 square inches
Finally, we can determine the number of bricks needed by dividing the area of the wall by the area of one brick:
Number of bricks = Area of the wall / Area of one brick
= 4752 square inches / 24 square inches
= 198 bricks
Therefore, it will take 198 bricks to complete the brick wall.
