Hello!
You can separate the image into two shapes, a trapezoid and a parallelogram
To find the area of a trapezoid you use the equation
[tex] \frac{a+b}{2} h[/tex]
a is base 1
b is base 2
h is height
Put in the values you know
[tex] \frac{11 + 8}{2} * 4[/tex]
Add
[tex] \frac{19}{2} * 4[/tex]
Divide
9.5 * 4 = 38
Next you find the area of the parallelogram
To find the you use the equation
bh
b is base
h is height
Put in the values you know
11 * 8.2 = 90.2
Add the two areas together to get the area of the whole shape
90.2 + 38 = 128.2
The answer is 128.2
Hope this helps!
