I need to know how to find the Area :)

Explanation
to solve this divide the figure into 3 rectangles, so
Step 1
find the area of the rectangles
the area of a rectangle is given by:
[tex]\begin{gathered} \\ \text{Area}_{rec\tan gle}=length\cdot widht \end{gathered}[/tex]then, find the areas
let
a)Rectangle 1(blue)
length=12
width=4
[tex]\begin{gathered} Area_1=12\cdot4 \\ Area_1=48\text{ square meters} \end{gathered}[/tex]b)
Rectangle 2
length=12
width=3
[tex]\begin{gathered} Area_2=\text{ 12}\cdot3 \\ Area_2=36\text{ square meters} \end{gathered}[/tex]c)
Rectangle 3
Length=5
Width=12-4-5=3
[tex]\begin{gathered} \text{Area}=5\cdot3 \\ \text{Area}=15\text{ square meters} \end{gathered}[/tex]Step 2
find the total area
[tex]\begin{gathered} \text{total area= Area}_1+Area_2+Area_3 \\ \text{replace} \\ \text{total area= (48+36+15)m}^2 \\ \text{total area=99 square meters} \end{gathered}[/tex]I hope this helps you
