Question

PLEASE HELP ME THIS IS DUE TODAY! :(

The length of Rectangle 1 is 3.2 x 10^5 m. The width of Rectangle 1 is 1.6 x 10^4 m. What is the area of Rectangle 1? Write the answer in Scientific Notation.

Find the area of Rectangle 2 if its length is 1.28 x 10^7 m and its width is 8 x 10^3 m. Write the answer in Scientific Notation.

Answer 1

5.12×10⁹ and 1.024×10¹¹

Explanation:

area of rectangle 1 :

(3.2 × 10⁵)(1.6 × 10⁴) = (3.2×1.6)(10⁵×10⁴)

=5.12× (10^5+4)

=5.12×10⁹

area of rectangle 2 :

(1.28×10⁷)(8×10³) = (1.28×8)(10⁷×10³)

= 10.24×(10^7+3)

= 10.24×10¹⁰

=1.024×10¹¹

Answer 2

Rectangle 1 ) 5.12E9m Rectangle 2 ) 1.024E11m

Explanation:

• Rectangle 1:

(3.2 x 10^5) x (1.6 x 10^4) = 5.12E9

• Rectangle 2:

(1.28 x 10^7) x (8 x 10^3) = 1.024E11
