Question

the area of the rectangle is X square + 12 X Y + 27 y square and its length is X + 3 Y find the breadth of the rectangle​

Answer 1

Here.

area of rectangle is given =x²+12xy+27y²

Length of rectangle =x+9y

then area of rectangle =length x breadth

x²+12xy+27y² =x+9y x breadth

X²+9xy+3xy+27y² =x+9y x breadth

x(x+9y)+3y(x+9y) =x+9y x breadth

(x+3y) (x+9y) =x+9y x breadth

breadth = x+3y anwer
