Answer:
36 square feet,
Step-by-step explanation:
Given:
Mr Thomas wants to protect his garage by installing a flood barrier.
He connects 2 barriers side by side
Each barrier is 9 feet long by 2 feet high ( breadth)
Question asked:
What is the combined area of the barriers ?
Solution:
Length of each barrier = 9 feet
As he connects 2 barriers side by side, the length will be doubled but height (breadth) will be unchanged.
Total length of two barriers = 9 + 9 = 18 feet
Height (breadth) of the barriers = 2 feet
By using, Area of rectangle =
=
Therefore, combined area of the barriers is 36 square feet,
