3.9 and 5.3, when rounded off and mult. together, produce the product 20.
Thus, the decimal point must follow the first two digits of your answer, whether estimate or "exact."
3.9*5.3 = 20.67 by calculator.

Answer:
5
Step-by-step explanation:
4.5*10^-8/ 9*10^-9
1) Reduce the fraction, express 9 as a product of multiplying 4.5*2
4.5*10^-8/4.5*2*10^-9
2) Then notice the common factor of numerator and denominator( 4.5) , get rid of it in both numerator and dnominator
3) 10^-8/ 2*10^-9= 1/2*(10^-8/10^-9)= 0.5* (10^-8/10^-9)
10^-8/10^-9= 10^(-8-(-9))= 10^1=10.
so 0.5*10=5 (it is the answer written in scientific form)
The perimeter is 988 meters
Further explanation:
The given square has different length and breadth which means that the given square is a rectangle.
The formula for perimeter of a rectangle is:
![P=2L+2W](https://tex.z-dn.net/?f=P%3D2L%2B2W)
Given
Length=L=256m
Breadth=W=238m
Putting the values in the formula:
![P=2(256)+2(238)\\=512+476\\=988\ meters](https://tex.z-dn.net/?f=P%3D2%28256%29%2B2%28238%29%5C%5C%3D512%2B476%5C%5C%3D988%5C%20meters)
The perimeter is 988 meters.
