Formula for calculating the area of a rectangle A = Length *width
For statement A;
Given area of a rectangle with measured length = 2.536 mm and width = 1.4 mm.
Area of the rectangle = 2.536mm * 1.4mm
Area of the rectangle = 3.5504mm²
The rule of significant figures states that we should always convert the answer to the least number of significant figure amount the given value in question. Since 1.4mm has 2 significant figure, hence we will convert our answer to 2 significant figure.
Area of the rectangle = 3.6mm² (to 2sf)
For statement B;
Given area of a rectangle with measured length = 2.536 mm and width = 1.41 mm.
Area of the rectangle = 2.536mm * 1.41mm
Area of the rectangle = 3.57576mm²
Similarly, Since 1.41mm has 3 significant figure compare to 2.536 that has 4sf, hence we will convert our answer to 3 significant figure.
Area of the rectangle = 3.58mm² (to 3sf)
Based on the conversion, it can be seen that 3.6mm² is greater than 3.58mm², hence the area of rectangle in statement A is greater than the area of the rectangle in statement B.
Answer:
Furniture mover.
Explanation:
A strain is a soft tissue injury that happens on the muscle or tendon - it could occur on several parts of the body, such as hands or legs. When it is acute, an incident might have caused it and proper rest would let it heal.
This type of injury could happen to athletes, but those who are at risk are those who are involved in sports field such as wrestling and football. Thus, baseball players are a lower risk.
Bank tellers and heart surgeons would not suffer from this type of injury - they are more likely to suffer from chronic than acute strains do to the overuse of certain muscles.
The group that is at the highest risk are people who move heavy objects - such as furniture mover.
