Can someone please explain Question 8, and how to do it? Thank you!!:)

Proof for the equations are given below.

Step-by-step explanation:

Area of a square = (side length)²

Here, the length of the side of the larger square = a + b

⇒ Area of the square = (a + b)²

Here, the side of the square = a - b

⇒ Area of the square (in the center) = (a - b)²

Area of a rectangle = length × width

Here, length = a and width = b

⇒ Area of the 4 rectangles = 4 × a × b = 4ab

∴ Sum of the areas = (a - b)² + 4ab

Now, both these areas are the same.

⇒ (a - b)² + 4ab = (a + b)²

Left Hand Side =  (a - b)² + 4ab = a² - 2ab + b² + 4ab = a² + 2ab + b²

                                                    = (a + b)²

                                                    = Right Hand Side of the equation

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

no i do not : ( what is it?
