The best way to go about this is to break the shape down in shapes you already know how to solve the areas for.
Lets break this into a rectangle and two triangles:
Area of the Rectangle:
A = L • W
where L is length and W is width.
For length, lets use 3.6 cm.
For width, lets use 5.9 cm
A = 3.6 • 5.9
A = 21.24 cm squared
Area of a Traingle:
A = 1/2 b • h
where b is base and h is height.
Let’s first find the area if the triangle on the left side of the shape.
b = 1.1 cm
h = 4.8 cm
Plug this in to the area equation:
A = 1/2 • 1.1 • 4.8
A = 2.64 cm squared
Finally, let’s find the area of the triangle at the top of the shape. This one requires a bit more work, but nothing too hard.
First, find the base by subtracting the length value of the rectangle from the height value of the previous triangle:
4.8 - 3.6 = 1.2 cm
The base of this triangle is 1.2 cm, and the height of this triangle also happens to be the width of the rectangle, 5.9 cm:
b = 1.2 cm
h = 5.9 cm
Plug this into the area of a triangle equation:
A = 1/2 • 1.2 • 5.9
A = 3.54 cm squared
Now for the entire area of the original shape, add these three areas together:
A = 21.24 + 2.64 + 3.54
A = 27.42 cm squared
The area of this shape is 27.42 cm squared.
Hope this helps!
