Of multiplication or addition?
Hi there! The answer is B.
First work out the parenthesis.
Next collect the terms.
The answer is B.
For this case we first calculate the area of the complete rectangle.
We have then:
A1 = (8.5) * (11)
A1 = 93.5
Then, we calculate the area of each circle:
A2 = pi * r ^ 2
A2 = (3.14) * (2/2) ^ 2
A2 = 3.14
The total area is given by:
A = A1 - 4 * A2
A = 93.5 - 4 * (3.14)
A = 80.94 in ^ 2
Answer:
A) 80.94
