The area of the shape can be calculated using the formula:


A=l* w

From the diagram, both the length and the width are 10 units long. Therefore, the area can be given to be:


A=10*10

By arithmetic, we have that:


10=7+3

Therefore, we can rewrite the expression for the area to be:


A=10*(7+3)

Recall the distributive property:


a(b+c)=a* b+a* c

Therefore, the expression can be rewritten to be:


\begin{gathered} A=(10*7)+(10*3) \\ or \\ A=(3*10)+(7*10) \end{gathered}

The LAST OPTION is correct.
