84 = 2(l+b)
L+b = 84 / 2

Length is 42 and breadth is 42 - 8
Divide the number by 1,000,000 (1 million).
Micrometer is a millionth of a meter
11,562/1,000,000 = 0.011562
Cost of 32 ounces yoghurt = $1.62
Cost of 1 ounce = $1.62/32 = $0.05 (approx)
Move the decimal to the right 11 times. 2,456,00,000,000
