Question

The length of a rectangle is x units. Its breadth is 6 units less than its length. Find a rule to
determine its area.
​

Answer 1

Answer:

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 !!

Answer 2

Question

The length of a rectangle is x units. Its breadth is 6 units less than its length. Find a rule to determine its area.

Answer

length = x units

breadth = 6 less than it's length = (x-6) units

_________________

There,

area of the triangle =

= (1/2) × length × breadth

= (1/2) × (x) × (x-6)

= (x²-6x)/2

________________________

Therefore, area of the triangle is (x²-6x)/2, for any value of 'x'.
