How many different rectangles can you draw with an area of 28? what is the perimeter of each one?

You can draw three rectangles:

1- 28 * 1.

2- 14*2

3- 7*4

The permeters will be:

P1 = 2*1 + 2*28 = 58

P2 = 2*2 + 2*14 = 32

P3 = 2*4+2*7 = 22

Step-by-step explanation:

We have a total area of 28. If we use only integer numbers, we can find all the divisors of 28. The possible rectangles will be organized with them, taking into account that the product of them, which means the area should be 28.

28 = 1*2*2*7

We can organize them as follows:

R1: 28 = 1*28

R2: 28 = 2*14

R3: 28 = 4*7

Those are the three posible rectangles. The permeters will be:

R1 P1 = 2*1 + 2*28 = 58

R2 P2 = 2*2 + 2*14 = 32

R3: P3 = 2*4+2*7 = 22.

Finally, we can conclude that You can draw three rectangles:

1- 28 * 1.

2- 14*2

3- 7*4

The permeters will be:

P1 = 2*1 + 2*28 = 58

P2 = 2*2 + 2*14 = 32

P3 = 2*4+2*7 = 22

what "following statement"?

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
