Question

I need help with finding the area of thisDo please explain though (I’ve got other questions like that and I want to be able to do it on my own)

Answer 1

The area is:

`A=x^2+8x+15`

Explanation:

Remember that we calculate the area of a rectangle by multiplying its lenght by its width, as following:

`A=l* w`

Now, notice that the given rectangle has a lenght of:

`x+5`

And a width of:

`x+3`

This way, the area would be:

`\begin{gathered} A=(x+5)(x+3) \\ \rightarrow A=x^2+3x+5x+15 \\ \\ \Rightarrow A=x^2+8x+15 \end{gathered}`
