22)

  • [tex]2(length+breadth+h)[/tex]
  • [tex]2(5a^2b^2+3ab^2)[/tex]
  • [tex]Perimeter: 2ab^2(5a^2+31)[/tex]

[tex]Area:-[/tex]

  • [tex]5a^2b^4 *3ab^2[/tex]
  • [tex]A=15a^2b^6[/tex]

-----------

23)

[tex]perimeter:-[/tex]

  • [tex]4m^2+3mn^2+7mn[/tex]
  • [tex]4m^2+10mn^2[/tex]
  • [tex]answer: 2m(2m+5n^2)[/tex]

[tex]Area:-[/tex]

  • [tex]\frac{1}{2}* base* height[/tex]
  • [tex]1/2*3mn^2*4m^2[/tex]
  • [tex]6mx^{2+1}n^2[/tex]
  • [tex]A=6m^3n^2[/tex]

----------

24)

  • [tex]1/2*b*h[/tex]
  • [tex]1/2x^24m^2*8mn[/tex]
  • [tex]A=16m^3n[/tex]

----------

25)

  • [tex]1/2*(7a^2b+11a^2b)*3ab[/tex]
  • [tex]1/2*18a^2b*3ab[/tex]
  • [tex]9a^2b*3ab[/tex]
  • [tex]A=27 a^3b^2[/tex]

------------

26)

  • [tex]A= 9\pi (x^3y)^2[/tex]

∴To calculate the perimeter , add the length of its sides.

∴To calculate the area, multiply its height by its width.
