from the sheet of paper?



PLZ ANYBODY GIVE ANSWER THIS QUESTION​

Answer 1

Answer:

find out the area of the square sheet= l*b

30*21=630 cm

now,

perimeter of square =side*4

divide the area of rectangle by 4

so,

630/4

Answer 2

Answer:

we know

21*30=630

we take each side of 5 cm.

so,

5*5=25

area of one square is 25cm square.

hence,

630 - 5 =625

so,

625÷25 =25 .

we get 25 square and 5 cm square paper remain.
