Question

A rectangular is made of gray and white square tiles as shown. Choose all the expressions that can be used to find the area of the rectangle A. 3×2+3×4B. 3×2+4 C. 3×6 D. 3+2+4E. 3+2+3+4May you please explain me this and why?

Answer 1

The area of a rectangle is given by:

`\begin{gathered} A=w\cdot h \\ Where\colon \\ A=Area \\ w=width \\ h=Height \end{gathered}`

So, the area of this rectangle is:

`\begin{gathered} A=w\cdot h \\ w=2+4=6 \\ h=3 \\ so\colon \\ A=3*6=18 \\ or \\ A=(2+4)*3=3*2+3*4=18 \end{gathered}`

So, the answers are:

`\begin{gathered} 3*6 \\ and \\ 3*2+3*4 \end{gathered}`
