Answer:
Step-by-step explanation:
Mr Thompson wants to protect his garage by installing a flood barrier. He connects 2 barriers side by side. The length of each flood barrier is 9 ft while the height of each barrier is 2 ft. The barriers are rectangular in shape. The area of each rectangular barrier is expressed as length × height.
Therefore
Area of each barrier is 9 × 2 = 18 ft^2
The combined area of the barriers would be
18 × 2 = 36 ft^2
