Mr thompson wants to protect his garage by installing a flood barrier. He connects 2 barriers side by side. Each barrier is 9 ft long by 2 ft high. What is the combined area of the barriers?

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
