WebThe answer is calculated by multiplying 10.5 inches by 4. The number 10.5 has 3 significant figures. The number 4 is an exact number; you count, and not measure, that there are 4 sides to a square. The number of sides is thus considered to have an infinite number of sig figs and should not limit the certainty of the perimeter. Weba) multiply 3.1 by 3.5. Each number has two significant figures therefore the answer can have a maximum of two significant figures. 3.1 x 3.5 = 10.85. However 10.85 has four significant figures and therefore must be rounded to 11, which has two. So in this case the correct answer is 11.
