Question

Find the PERIMETER and AREA of each figure below

Answer 1

Answer:

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)

$perimeter:-$

• $4m^2+3mn^2+7mn$

• $4m^2+10mn^2$

• $answer: 2m(2m+5n^2)$

$Area:-$

• $\frac{1}{2}* base* height$

• $1/2*3mn^2*4m^2$

• $6mx^{2+1}n^2$

• $A=6m^3n^2$

----------

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.
