Answer 1

Step-by-step explanation:

Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.

The rule apply for the multiplication and division is :

The least number of significant figures in any number of the problem determines the number of significant figures in the answer.

`(52.6cm)* (1.214cm) = 63.8564 cm^2`

So ,the answer will be 3 significant figure =
`63.9 cm^2`

Answer 2

In case of multiplication and division, the significant figures of the answer should be equal to the given with the lowest significant figure. We are given that:

(52.6 cm) * (1.214 cm)

The lowest significant figure is 3, therefore the answer is:

(52.6 cm) * (1.214 cm)

= 63.9 cm^2
