Finding the original price: the grocer settled some old accounts for 16% less than the original amounts. on this basis she collected $1680. what was the total of the original accounts ?

D) Area of green + Area of red square = Area of yellow square

Step-by-step explanation:

Given : Given: a² + b² = c²  and The quadrilaterals in the diagram are squares.

To find : Area of green  + area of red = ?

Solution : We have given that Three square green , red and yellow.

Side of square green = a

Area of green = a²

Side of square Red = b.

Area of red square = b²

Side of square yellow = c

Area of yellow square = c²  .

Triangle blue is right angle triangle by Pythagorean triangle

(Hypotenuse)² =  a² + b².

c²  =  a² + b².

We can see

Area of yellow square = Area of green + Area of red square.

Therefore, D) Area of green + Area of red square = Area of yellow square
