A vernier callipers is used to measure the width and the length of a rectangular plate. The measured values are 1.38 cm and 4.02 cm respectively.Find the uncertainly in the value of its area.

The length and breadth of a rectangular plate are measured to be 14.5 cm and 4.2cm respectively. Find its area to appropriate significant figures.

The length and breadth of a rectangular plate are measured to be 14.5 cm and 4.2cm respectively. Find its area to appropriate significant figures.

If the length and breadth of a thin rectangular sheet are measured, using a metre scale as 16.2 cm and 10.1 cm respectively. What is the area of the rectangular sheet.

If the length and breadth of a thin rectangular sheet are measured, using a metre scale as 16.2 cm and 10.1 cm respectively. What is the area of the rectangular sheet.

To calculate the volume of cylinder, a student is given a metre scale of least count 1 mm to measure its length and vernier callipers of least count 0.1 mm to measure its diameter. If its length and radius are 10 cm and 2 cm respectively then the percentage error in the calculated value of the volume of the cylinder will be

The length and breadth of a plate are (6 pm 0.1) cm and (4 pm 0.2)cm respectively. The area of the plate is
