Answer: 14.25 ft
Step-by-step explanation:
Assuming all the bricks used are red:
Keith puts 19 bricks end to end along a sidewalk and each one of those bricks is 0.75 ft long.
When put end to end therefore, the total length will be that length multiplied by the number of bricks laid:
Total length = Number of bricks laid * Length of each brick
= 19 * 0.75
= 14.25 ft
