Answer:
a=28m^2
Step-by-step explanation:
Given:
l=14m
w=200cm
Required
a=?
w in meters
Formula:
1m=100cm
b=200cm---criss cross it
b*100cm/100cm=1m*200cm/100cm
b=2m
a=l*w
a=14m*2m
a=28m^2

You need one equation of this problem to balance the amount of a boric acid.
The amount of boric acid in 50% solution is expressed as 0.50*x
Next, the amount of water is taken from 25 liters and x (based on 50% solution), that is 25 - x. However, there is NO amount of BORIC ACID in water, and that is 0.
For the output solution, the amount of boric acid will be 0.10*2.5 = 2.5
Then, the balance equation is
0.50*x + 0*(25 - x) = 2.5
Solving for x,
0.50*x + 0 = 2.5
x = 2.5/0.5 = 5
Therefore the amount of liters in 50% solution is
5*0.50 = 2.5 liters
The amount of water is 25 - 5 = 20 liters
Break apart the solid figure into two rectangular prisms.
then Find the length, width, and height of each prism.
Find the volume of each prism.
the you add the volume of each prism.
hoped i helped :D
