Answer:
Step-by-step explanation: 1.1)The length is 3 and the breadth is x.. hence, A= 3[tex]x^{}[/tex] (3 x [tex]x^{}[/tex])
1.2) Length is x and so is the breadth.. hence, A= [tex]x^{2}[/tex] ([tex]x[/tex] x [tex]x[/tex])
1.3) Length is x and breadth is 2... hence, A= 2[tex]x[/tex] (2 x [tex]x[/tex])
1.4) Length is 3 and breadth is 2.. hence, A=6 (3 x 2)
1.5) Now we need add all of these..
3[tex]x^{}[/tex] + [tex]x^{2}[/tex] + 2[tex]x[/tex] + 6
= [tex]x^{2} + 5x + 6[/tex]..
Im pretty sure you need to leave it like this.. if u have not learnt quadratic equations.. if you have then pls get back to me
