Answer:
608 cm²
Step-by-step explanation:
Find the area of the 3 rectangles.
Rectangle 1 = 10 x 16 = 160
Rectangle 2 = 16 x 12 = 192
Rectangle 3 = 16 x 10 = 160
Now find the area of the triangle using the formula:
[tex]\frac{1}{2\\}[/tex] x Base x height
= [tex]\frac{1}{2\\}[/tex] x 8 x 12 = 48
Both the triangles are similar, so you don't have to calculate again.
Finally add all the areas to get the surface area.
160 + 192 + 160 + 48 + 48 = 608 cm²
