Answer:
6.5 * 10 ^ -9
Step-by-step explanation:
0.0000000065
Scientific notation means a* 10 ^b
where a is number between 1 and less than 10
Move the decimal 9 places to the right which means the power of 10 is negative since we moved the decimal to the right
6.5
The power of 10 is -9
6.5 * 10 ^ -9
1000 = 2*length + 2*wudth
therefore
1000 = 2*150 + 2* width
width = ( 1000 - 300)/2
= 700/2
width = 350
