-
- according to the question
if x is the side of square and a and b are the sides of rectangle
then x^2 = 2(a*b) -------eq.1
since the rectangle share its 50% area ..so the length of the rectangle should be double to the side of the square
here, AE > AB
so, AE = 2x = a
and since the square share 25% of its area with rectangle, so its side should be 4 times the breadth of the rectangle
here, AD > AG
so, AG = x/4 = b
and a and b are satisfying eq.1 also
hence AE/AG = 2x/(x/4)= 8
it can be better understood after drawing the square and rectangle on paper with their shared areas - 10 years agoHelpfull: Yes(10) No(1)
- after visualizing the diagram
AE is collinear with AB
AG collinear with AD
let side of square is 4x, AB=4x
as 25% of area of square= 50% area of rectangle
AG = 14 AD
AG = x
AE = 2 AB
AE= 2x
AE/AG = 8x/x = 8/1 - 10 years agoHelpfull: Yes(6) No(0)
