Answer
Assuming the "length of 12.3 cm" refers to the area of the square (as indicated by the instruction to use square roots to find the side), the length of the side is approximately 3.51 cm.
Step-by-step solution
4 stepsSteps:
Interpret the given information
The problem states a "length of 12.3 cm" for a square and asks to find the "length of side" using "mathematical tables of square roots". This strongly implies that the 12.3 cm refers to the area of the square, despite the unit being given as cm instead of cm².
- Area (A) = 12.3 cm²
Formula for the side of a square
For a square, the area (A) is equal to the side length (s) squared (A = s²). To find the side length, we take the square root of the area.
- s = √A
Substitute and calculate
- s = √12.3 cm
- s ≈ 3.5071359 cm
Round to appropriate significant figures
The given value 12.3 has three significant figures. Rounding the result to three significant figures:
- s ≈ 3.51 cm
