Answer:
200 cm²
Step-by-step explanation:
Find the areas of all of the faces
17 × 2 = 34 (Top Face)
8 × 15 = 120 (Both Triangles)
15 × 3 = 30 (Bottom Face)
8 × 2 = 16 (Back Face)
Add them all together
120 + 34 + 30 + 16 = 200 cm²
The answer to this question is 0.4
They are both the same equations, the procedure to obtain x value will be equivalent.
The answer is 7 - 7.5
you multiply 5 and 3 and get 15 then divide by 2
