Answer: 32
But say we didn't know the formula. We can chop out the 4 by 4 square and we have two 45/45/90 triangles side 4 left over, so two 4 by 4 squares,
A = 2(4)(4) = 32
We can think of this as 12 by 4 rectangle with two 4 by 4 right triangles chopped out:
A = 12(4) - 2(1/2)(4)(4) = 48 - 16 = 32
Answer:
Step-by-step explanation:
has the form
known as a difference of squares. It factors into (a+b)(a-b). To find a and b you take the square root.
The factored for is (a+b)(a-b).
In this case, it is
