​

Answer 1

Step-by-step explanation:

Given :-

a rectangle with length (x+3) units and breadth (x-3)

To find:-

What is an equivalent expression for the area of a rectangle

Solution:-

Length of a rectangle= (x+3) units

Breadth of the rectangle= (x-3) units

Area of a rectangle= length×breadth sq.units

Area of the given rectangle= (x+3)×(x-3)

= x^2-9sq.units

(a+b)(a-b)=a^2-b^2)

(here ^ means power)

Answer:-

Equivalent expression for the area of the rectangle is (x^2-9) sq.units
