Question

Find the PERIMETER and AREA of each figure below

help ASPS
Find the perimeter and area 22-24 and only find the area for 25-26

Answer 1

22)

• 
  `2(length+breadth+h)`

• 
  `2(5a^2b^2+3ab^2)`

• 
  `Perimeter: 2ab^2(5a^2+31)`

`Area:-`

• 
  `5a^2b^4 *3ab^2`

• 
  `A=15a^2b^6`

-----------

23)

`perimeter:-`

• 
  `4m^2+3mn^2+7mn`

• 
  `4m^2+10mn^2`

• 
  `answer: 2m(2m+5n^2)`

`Area:-`

• 
  `(1)/(2)* base* height`

• 
  `1/2*3mn^2*4m^2`

• 
  `6mx^(2+1)n^2`

• 
  `A=6m^3n^2`

----------

24)

• 
  `1/2*b*h`

• 
  `1/2x^24m^2*8mn`

• 
  `A=16m^3n`

----------

25)

• 
  `1/2*(7a^2b+11a^2b)*3ab`

• 
  `1/2*18a^2b*3ab`

• 
  `9a^2b*3ab`

• 
  `A=27 a^3b^2`

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

26)

• 
  `A= 9\pi (x^3y)^2`

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

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