Answer:
Step-by-step explanation:
let us calculate area of pentagon.
it consists of 5 isosceles triangles with base=5 cm
apothem h=3.6 cm
area of pentagon=5×1/2×5×3.6≈45 cm
area of 2 pentagons (top and bottom)=2×45=90 cm²
lateral area of 6 rectangles=2(10×5+10×5+10×5)=2(50+50+50)=300 cm²
Total surface area=90+300=390 cm²

Answer:
-3.5x + 3y - 3
Step-by-step explanation:
1.2x + 3y - 3 - 4.7x
=> -3.5x + 3y - 3
Therefore, our simplified expression is -3.5x + 3y - 3
