Answer:
a = 162
Step-by-step explanation:
9 = 1/27 a +3
Subtract 3 from each side
9-3 = 1/27 a +3-3
6 = 1/27 a
Multiply each side by 27
6*27 = 1/27 a *27
162 = a

Answer:
0.00360.
Step-by-step explanation:
Leading zeros in a number are not significant, so your number has four significant figures.

R=104.
104/6=17.33333333333333
52/3=17.33333333333333

Lets first simplify the dimensions of the rectangle
length = 7
breadth = 

 = 

 = 0.6
The area of rectangle = length * breadth
so, area of rectangle = 7 * 0.6  
Area of rectangle = 4.2
Hope it helped you.. :D
