Answer 2

$Area \: of \: Sheet = l×b$

$= 70 \times 50$

$= 3,500 \: sq.cm$

$Length \: of \: Remaining \: Sheet \\ =70-10 \\ = 60 \: cm$

$Breadth \: of \: Remaining \: Sheet \\ =50 - 10 \\ = 40 \: cm$

$Area \: of \: Remaining \: Sheet \\ =60 \times 40 \\ = 2,400 \: sq.cm$

$Area \: of \: Strip \: to \: Cut \: out \\ = 3,500- 2,400 \\ = 1,100$
