The area of the shaded region
The correct answer is A.
Here is the set up:
Side 1 is 4x.
Side 2 is 5x + 3
Side 3 is 5x + 1
The perimeter is 102.
Perimeter = side 1 + side 2 + side 3
102 = 4x + 5x + 3 + 5x + 1
102 = 14x + 4
Take it from here.

Answer:
57,001 cm², or 5.7 square meters
Step-by-step explanation:
The surface area of a cylinder is given by the formula ...
A = 2πr(r +h)
A = 2π(14 cm)(14 cm +40 cm) = 1512π cm²
Then 12 cylinders will have an area of ...
12 × 1512π cm² = 18,144π cm² ≈ 57,001 cm²
Rui Feng wants to paint a total surface area of 57,001 cm², about 5.7 square meters.
