Question

A poster is 0.95m high and 1.0m wide how many digits follow the decimal point when the perimeter of the poster is expressed with the correct number of significant figures

A) zero digits
B) one digit
C)two digits
D)three digits

Answer 1

Step-by-step explanation:

It is given that,

Length of the poster, l = 0.95 m

Breadth of the poster, b = 1 m

The poster is in the shape of rectangle. For a rectangular shape, perimeter is equal to :

P = 2(l+b)

P=2(0.95+1)

P=3.9 m

(b) One digits, P = 4 m

(c) Two digits, P = 3.9 m

(d) Three digits, P = 3.90 m
