hello frnd!!
here's ur answer...
given:-
side of square=64m
length of rectangle=70m
breadth of rectangle=?
perimeter of square=perimeter of rectangle
perimeter of square=4×side
=4×64
=256m
perimeter of rectangle=256m
2(l+b)=256m
2(70+b)=256m
140+2b=256m
2b=256-140
2b=116m
b=116/2
b=58m
hence, breadth of the rectangle is 58m.
area of square=side×side
=64×64
=4096m²
area of rectangle=l×b
=70×58
=4060m²
area of square is more by=4096-4060
=36m²
hope this helps....
