the perimeter is 64ft and the width is 12ft and the length is x+6 what is the length

Sagot :

Answer:

The length is 20

Step-by-step explanation:

Assuming it is a rectangle:

 

Perimeter = 2 * length + 2 * width

 

64 =  2 * (x+6) + 2 * 12

 

64 = 2 * (x+6) + 24

 

40 = 2 * (x + 6)

 

20 = x + 6

 

x=14

 

The length is 20.

Answer:

length is 20 ft

Step-by-step explanation:

first we know that when we add all sides we get the perimeter so one side is 12 ft so it would be 64 ft - 24 ft and you are left with 40 ft for the rest of the perimeter which is two times x+6 because there are 2 remaining sides.

40= 2(x+6)

40= 2x + 12

-12 -12

28= 2x. divide by 2 both sides

14=x

so (14)+6=20
