Answer 1

Q 1 =>

perimeter = 64

formula we know as side^2

=> side = square root of 64 = 8


perimeter = side × 4


=> 8 × 4 = 32

( I AM DOING ONLY 1 FROM EACH. SO REST ALL U TRY. THEY ARE ALSO IN THE SAME PROCESS.)

Q2 =>



AREA of the metal plate = 32 × 12m^2

area of small squares = 4 × 4


=> total numbers of squares = 32 × 12 / 4 × 4 = 24


hence 24 squares can be done.

Q3 =>





AREA OF RECTANGLE = 24 × 17

= 408m^2



AREA OF SQUARE = 21 × 21m^2


==== 441m^2


DIFFERENCE = 441m^2 - 408m^2 = 33m^2


HENCE SQUARE 'S AREA IS GREATER THAN RECTANGLE BY 33m^2
