Question

The length of a plate as measured with a ruler is 24.74 cm. The breadth as measured with a Vernier caliper is 6.78 cm. Calculate the are of the plate with exact significant figures.

Answer 1

The area of the plate is 167.78 centimeters.

The area of the plate can be calculated with the equation of the area of a rectangle:

$A = l*w$   (1)      

Where:

l: is the length = 24.74 cm

w: is the width = 6.78 cm

By entering the above values into equation (1) we can find the area.

$A = 24.74 cm*6.78 cm = 167.74 cm$

Therefore, the area of the plate is 167.78 centimeters.
