Question

Lenght of rectangular is X unit is breath is 6 unit less than it lenght find a rule to determine its area

Answer 1

Let the length of the given rectangle = x units

Given : the breadth is 6 units less than its length

hence, breadth = (x-6) units

We know that the area of a rectangle = l*b

hence, area = x(x-6)

                    = (x²-6) sq.units

Hope it helps !!
