Question

A rectangular table size is 6 m x 12 m. Calculate its area in (micro-meter square). If we write it in scientific notation, what will be the power of 10? Mark the power as your answer.

Answer 1

Answer:

72

first multiply than cut that sum

Answer 2

Explanation:

here, first convert it into micro meter

6m= 6000 mm =6×10⁶ μm

12m = 12000mm = 12×10⁶μm

Now area of the rectangle = l×b

= 6×10⁶μm × 12×10⁶μm

= 72 × 10¹² μm²

= 7.2× 10¹³ μm²
