A warehouse had a square floor with are 10,000 sq.metres. A rectangular addition was built along
one entire
side of the warehouse that increased the floor by one-half as much as the original floor. How many
metres did
the addition extend beyond the original building?
A) 10 B) 20 C) 50 D) 200
E) 500

• length=100,b=?
  area of rectangle=l*b
  original floor=10,000 sq.metres
  increasing the original floor by half of the original floor=10000+1/2(10000)
  =15000
  so 15000-10000=5000(area of rectangular portion)
  l*b=5000
  l=100 so 100*b=5000 ->b=50
  so extended part is of 50metres

• area of square floor=10,000 = a^2
  then, a=100;
  increased floor length = 1/2*(original floor) => 1/2*(a)
  =>1/2*(100) => 50 metres //

• Ans 50
  100+50=l
  50=b

• (100+x)100=10000+10000*.5
  10000+100x=15000
  x=50
