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

i got 10.28 but that rounds up to 10.3
