Answer 1

9)

We are given:

The largest rectangle has 3 rectangles:

Rectangle 1 has a length of x & a width of 5

Rectangle 2 has a length of 2y & a width of 5

Rectangle 3 has a length of 3 & a width of 5

The area is given by:

$\begin{gathered} A=l\times w \\ A=x\cdot5+2y\cdot5+3\cdot5 \\ A=5x+10y+15 \\ \\ \therefore Area=5x+10y+15 \end{gathered}$

OR

$\begin{gathered} Area=length\times width \\ Area=5(x+2y+3) \\ \\ \therefore Area=5(x+2y+3) \end{gathered}$
