I assume by the length you mean height so,

≈ <span>4.54
.
if you're supposed to round it, it'd be either 4.50, or 5
</span>
I hope this helps
Step-by-step explanation:
area of a parallelogram is b×h
2.4×1=2.4cm²
I would appreciate if my answer is chosen as a brainliest answer
You're asking
(10⁶) times (10^p) = 10¹⁸ .
When you multiply two numbers that have the same base
but different exponents, you just add the exponents.
So 6 + p = 18
Subtract 6 from each side: p = 12 .
10⁶ x 10¹² = 10¹⁸ .
