Question

find the area of a square whose side is (2x-y) unit??​

Answer 1

Answer:

The area of rectangle=a×b=(2x+3y)(3x+2y)=(6x

2

+6y

2

+13xy)

area of square =a

2

=(x+y)

2

=(x

2

+y

2

+2xy)

therefore remaining area is equal to area of rectangle−area of square=(6x

2

+6y

2

+13xy)−(x

2

+y

2

+2xy)=(5x

2

+5y

2

+11xy)
