Question

find the length and breadth of a rectangle
whose length, breadth and area are
2X+1, X-3 and a squnits respectively​

Answer 1

Step-by-step explanation:

Area of Rectangle = l×b

= (2x + 1) (x - 3)

= 2x^2 - 5x- 3

= 2x^2 - 6x + x - 3

= 2x(x - 3) +1(x - 3)

= (x - 3) (2x +1)

Length = 3

Breadth = 7

Area = 3 × 7 = 21 sq units
