Answer:
GiveN:
The adjacent sides of the sandwich are of length 2x² + 9 and 2x² + 8.
To FinD:
Length of the crust of the sandwhich?
If x = 1.2, approximate length of crust...?
Step-wise-Step Explanation:
The crust is the hard brown layer surrounding the sandwhich. To find the length of the crust, we need to find the perimeter of the rectangle.
Rectangle have two pairs of equal sides. To find the perimeter, we can add all these sides that will be equal to 2(Length + Breadth).
By applying the formula,
⇒ Length of the crust = 2(l + b)
⇒ Length of the crust = 2(2x² + 9 + 2x² + 8)
⇒ Length of the crust = 2(4x² + 17)
⇒ Length of the crust = 8x² + 34
Now if x = 1.2, What will be the approximate value of the length of the crust:
⇒ 8(1.2)² + 34
⇒ 8(1.44) + 34
⇒ 11.52 + 34
⇒ 45.52 cm
Hence, The correct option will be Option B) 8x² + 34 and 45.52 cm. And we are done :)
