The identity property of multiplication is also known as the multiplication property of 1.
This states that the result of multiplying any real number by 1 is the number itself.
Here, the teacher wrote 6 people($0) = $0
This will be 0 as any number multiplied by 0 is 0. And here there is not 1. So, this expression is not an example of the identity property of multiplication.
the base is 6 inches, the height is 4.5 inches. Multiply that by usinhg the formula A = bh your answer will be 27 then multiply that by 60 and your answer is 1,620.
