Question

PLEASE HELP!!!! I AM STUCKK !A company is designing a rectangular computer chip that is 7.18 × 10−7 meters long and 3.4 × 10−9 meters wide.
Part A: Determine the area of the computer chip. Show every step of your work. (3 points)

Part B: Write the area in scientific notation with the correct number of significant digits, and label with the appropriate units. (3 points)

Part C: Determine the perimeter of the computer chip. Show every step of your work. (3 points)

Part D: Write the perimeter in scientific notation with the correct number of significant digits, and label with the appropriate units. (3 points)

Answer 1

part A) since the chip is rectangular, multiply length * width to get the area. multiply the non-exponential parts first (7.18 * 3.4) and then multiply the exponents (keep the base, add the exponents)

part B) convert your answer from part A to scientific notation. remember that scientific notation takes the form a * 10^(x) where a is a number at least 1 but less than 10, and x is a positive or negative integer. take your answer from part A, move the decimal point as needed, and adjust the exponent accordingly.

part C) perimeter = 2(length + width). because the length and width have different exponents, you'll need to convert them both to the same exponent to add them. for example, to convert 7.18 × 10^(-9) to exponent -7, you're multiplying the 10^(-9) by 10^2 to increase the exponent by 2. after that you'll need to divide 7.18 by 10^2 to keep the overall value the same.

part D) similar to part B, convert the answer from part C to scientific notation
