Answer: [tex]1.000\times 10^2m^2[/tex]
Explanation:
Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.
The rule apply for the multiplication and division is :
The least precise number present determines the number of significant figures in the answer.
The rule apply for the addition and subtraction is :
The least precise number present after the decimal point determines the number of significant figures in the answer.
Area of square collector 1 =
Area of square collector 1 =[tex]6.00m\times 6.00m=36.0m^2[/tex]
Area of square collector 2 =[tex]length\times breadth[/tex]
Area of square collector 2 =[tex]8.000m\times 8.000m=64.00m^2[/tex]
Combined area of both collectors = Area of square collector 1 + Area of square collector 2 = [tex]36.0m^2+64.00m^2=100.0m^2=1.0\times 10^2m^2[/tex]
The combined area of both collectors is [tex]1.000\times 10^2m^2[/tex]
