Given
area is the figure is (x+2)(x+9)
Find
another expression for this area by finding the sum of the areas od the smaller rectangles
Explanation
as we have given figure ,
area of rectangle ACEG = Area of rectangle ABIH +Area of rectangle BCDI + Area of rectangle DEFI + Area of rectangle IFGH
as we know Area of rectangle = length * breadth
so , Area of rectangle ACEG =
[tex]\begin{gathered} x\times x+x\times9+2\times x+2\times9 \\ x^2+9x+2x+18 \\ x^2+11x+18 \end{gathered}[/tex]Final Answer
Therefore , the area of the figure =
[tex]x^2+11x+18[/tex]
