Answer:
580 cm^2
Step-by-step explanation:
First, find the area of the front and back. 20*10=200
There are 2 sides with 20*10 ( front and back) so we can multiply by 2. 200*2=400
Then, the sides. 3*20=60*2=120
Then, the top and bottom 10*3=30*2=60
400+120+60=580

Let us consider , there are 30 boys and 40 girls in a school. So, the ratio of number of boys to number of girls =
and read as 3 is to 4. We can say , the ratio compares two of more quantities of same unit. Until two quantities have same units , it is meaningless to compare by ratio. So, to find the ratio of two quantities , it is necessary to express them in same unit or of same kind. Since , they are in division form. So ,ratio is unit less quantity. Thus , the ratio is a comparison of two quantities of the same kind in division which doesn't have any units. For example :
is a ratio and is read as ' a is to b ' in which ' a : is antecedent and ' b ' is called consequent.

Step-by-step explanation:
For
: (0,3) (2,2)
The equation is in slope intercept form. y=mx+b
The y intercept is 3.
The slope is 1/2.
Moving one unit down and 2 units to the right, we get (2,2)
For
: (0,-2) (1,0)
The y intercept is -2.
The slope is 2.
Moving 2 units up and 1 unit to the right, we get (1,0)
