Question

Heather has a rectangle poster that is 14 cm long and 10 cm wide. What is the area of the poster in square meters? Do not round your answer. Be sure to include the correct unit in your answer.

Answer 1

The area (A) of a rectangle is with sides a and b is:

`A=a*b`

Knowing that the sides are:

a = 14 cm = 0.14 m

b = 10 cm = 0.10 m

The area, in square meters, is:

`\begin{gathered} A=0.14*0.1 \\ A=0.014m^2 \end{gathered}`

Answer: 0.014 m².
