Question

dimension of rectangle are (x+y) and (x-y) express its area in terms of x. y

Answer 1

Answer:

The answer is $x^2-y^2$

Step-by-step explanation:

Formula:

Area of a rectangle is

     $=\boxed{\text{Product of dimensions of rectangle}}$

Hence required area

                    $=(x+y)(x-y)\\=x^2-y^2$

Using algebraic identity $(a-b)(a+b)=a^2-b^2$
