Answer:
27 feet
Step-by-step explanation:
Two walls have same area
Area of first wall(square) = 18*18 = 324
Area of second wall = 12 * x = 324
324/12 = 27
27 feet
To solve this problem, we must use the order of operations outlined by PEMDAS, which tells us that we should simplify or compute parentheses first, then exponents, multiplication, division, addition, and finally subtraction.
Using this method, we have to perform the multiplication inside the parentheses first.
(20 * 40) * 14
800 * 14
Finally, we must perform the final operation to simplify this expression, which is multiplication.
800 * 14 = 11200
Therefore, your final answer is 11200.
Hope this helps!
