The perimeter of a square and a rectangle is the same. If the rectangle is 12 cms. by 10 cms., then by what percentage is the area of the square more than that of the rectangle?
option
a) 1
b) 3
c) 5/6
d) 1/2

• perimeter of rectangle=2*(12+10)=44=perimeter of square
  so side of square=44/4=11
  area of rectangle=12*10=120
  area of square=11*11=121
  reqd%=(121-120)/120 *100=100/120=5/6

• c)5/6
  aeea of rect.=120
  area of sq. =121
  (121-120)/120*100=5/6

• perimeter of rectangle = 2(12+10)
  perimeter of rectangle = perimeter of square
  side square = 44/4
  are of rectangle = 12*10
  area of square = 11*11
  are of square-area of rectangle = 121-120=1
