Answer:
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]
-----------
23)
[tex]perimeter:-[/tex]
- [tex]4m^2+3mn^2+7mn[/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]
----------
24)
- [tex]1/2x^24m^2*8mn[/tex]
----------
25)
- [tex]1/2*(7a^2b+11a^2b)*3ab[/tex]
- [tex]1/2*18a^2b*3ab[/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.
