A square is cut into three equal rectangles. How does the area of the square compare to the sum of the areas of the three rectangles? A)sum of the areas of the rectangles equals the area of the square
B)area of the square is 3 times the sum of the area of the rectangles
C)sum of the areas of the rectangles is 3 times the area of the square
D)sum of the areas of the rectangles is

A?

Step-by-step explanation:

If the square was split into 3 rectangles the 3 rectangles sum up to the square.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
