To find the surface area of any object, the first step that you must do is find all shapes that are present in the object.
Here we have 2 triangles and 3 rectangles.
Knowing this, simply find the area of each shape.
Since the triangles are the same, one is facing up and the other down, they both would be 15.6 cm^2.
The rectangles would be 54 cm^2. as there are 3 ( 6 x 3 cm) ones.
Add the values up to have the surface area.
It’s 85.2 cm^2.
I believe the answer to your question is the first choice.
Since we have two sides that are 24 mm that means that the equation needs to have 2(24 mm).
And since we have 4 sides that are 18 mm, it means that the equation needs to have 4(18 mm).
so we get: P= 4(18 mm) + 2(24 mm)

Answer:
Total = 30.75cm squared
Step-by-step explanation:
Area of trapezium = (A+b)h divided by 2 = 15cm squared
area of triangle 1 = 1/2 x b x h = 3 cm squared
Area of triangle 2 = 2.25 cm squared
Area of trapezium at the bottom = 10.5 cm squared
Total = 30.75cm squared
