b^2-c^2 is area of rectangle

Answer 2

Answer:

Step-by-step explanation:

Let the length = (b + c)

            breadth = (b- c)

Area of rectangle = l × b sq.units

                             = (b+c) (b-c)

[Using the formula, (a+b) (a-b) =  a² - b²]

                              = (b² - c²) cm²
