Question

Area = Length x Width = (3.2×10^4) (2.5×10^6) = a) 8×10^10 b) 8×10^9 c) 8×10^7 d) 8×10^6

Answer 1

The area of the rectangle is (3.2x10^4) x (2.5x10^6) which simplifies to 8x10^10.

Step-by-step explanation:

The area of a rectangle can be found by multiplying its length and width. In this case, the length is 3.2x10^4 and the width is 2.5x10^6. To multiply two numbers in scientific notation, you multiply their coefficients and add their exponents. So, (3.2x2.5) x (10^4 x 10^6) = 8 x 10^10. Therefore, the correct answer is a) 8x10^10.
