Question

If a rectangle has side lengths of 3 cm and 4 cm, what is its area?

Answer 1

We have the following:

The area of the rectangle is equal to the product of its sides, that is, the length times the width

`A=l\cdot w`

In this case, l = 4 cm and w = 3 cm

replacing:

`\begin{gathered} A=4\cdot3 \\ A=12 \end{gathered}`

Therefore the area is 12 square centimeters
