A chocolate wrapper is 6.7 cm long and 5.4 cm wide

Question

A chocolate wrapper is 6.7 cm long and 5.4 cm wide. Calculate its area up to a reasonable number of significant figures.

$(36 cm^{2})$

Accepted Answer

Solution:

Length of the chocolate wrapper I = 6.7 cm

Width of chocolate wrapper w = 5.4 cm

Area = A = ?
Area = $Length imes Width$
A = $l imes w$
A=$6.7cm imes5.4$ cm = $36.18 cm^{2} = 36cm^{2}$

Note:
The answer should be in two significant figures because in data the least significant figures are two therefore answer is 36 $cm^{2}$
