Question

the length of the square field is
(2x-3y)cm then find the area of square in the form of algebraic expression

Answer 1

Answer:

Step-by-step explanation:

length of square field = (2x-3y) ; lets take this as 'a'

and area of square = a²

so area of this square = (2x-3y)²

using identity (a-b)²=a² + b² -2ab

(2x-3y)² = (2x)² + (3y)² - 2*2x*3y

               =  4x² + 9y² - 12xy        ----- ans

Answer 2

area of this square = (2x-3y)²

using identity (a-b)²=a² + b² -2ab

(2x-3y)² = (2x)² + (3y)² - 2*2x*3y

                =  4x² + 9y² - 12xy
