Answer 1

$\huge \sf \bf {\blue {\boxed{\underline {\pink{\underline {✠Aɴʂᴡᴇʀ࿐ :−}}}}}}$

let it be a

2xy : x2 = y2 : A

⇒ 2xy/x2 = y2/A

⇒ A = x2y2/2xy

⇒ A = xy/2

Answer 2

Answer:

4th proportion = (2nd ×3rd) ÷1 st

• so, 4th proportion of 2xy , x² and y² is
• = (X² ×Y² ) ÷2XY
• = ( XY ) ² ÷2XY
• = XY ×XY / 2XY
• = XY /2
