Answer:
120cm²
Step-by-step explanation:
The diagram of her garden is in the form of a trapezium.
The formula for the area of a trapezium is (a+b)*h/2
In the diagram, a=11, b=19, c (the height) is 8
so substituting these values in the formula-(11+19)*8 all divided by 2
This gives us 120cm²

Given:
[tex]11\ cm\\\\ 10\ cm \\\\ 8\ cm \\\\ 19\ cm\\\\[/tex]
To find:
area=?
Solution:
Her garden is drawn in the shape of a trapezium.
The area of a trapezium= [tex]\frac{(a+b)*h}{2}[/tex].
In the diagram:
[tex]a=11\\\\ b=19\\\\ c (height)=8[/tex].
As only a result of putting these numbers inside the formula:
[tex]\to \frac{(11+19)\times 8}{2} \\\\\to \frac{(30)\times 8}{2} \\\\\to \frac{240}{2} \\\\\to 120 \ cm^2\\\\[/tex]
Therefore, the answer is "[tex]120 \ cm^2[/tex]"
