Sagot :

Answer:

100 (I believe)

Step-by-step explanation:

The length would be 20
20 x 2 (because we have two sides) is 40

the width would have to be 5 then

5x2 (because we have to sides) is 10

5x4 is 20 (Showing that the length is 4 times the width)

40 + 10 = 50 (Which is the perimeter)

Since we know the length is 20 and the width is 5

we just do

20 * 5 = 100

Answer:

L = 20

Width = 5

Step-by-step explanation:

"The perimeter of the rectangle is equal to 2 times length + 2 times width:

 

P = 2L + 2W

 

We know that length is 4 times the width, so L = 4 W

 

We can now replace l by 4W in the equation of the perimeter:

 

P = 2L + 2W = 50

P = 2(4W) + 2W = 50

P = 8W + 2W = 50

P = 10W =50

 

So W = 50 /10

W = 5

 

And L = 4W

L= 4 (5)

L = 20"

2O × 5 = 100
