A rectangle is 4 times as long as it is wide. The perimeter of a rectangle is 50 cm. What are the dimensions of the rectangle?

5 cm ( width ) , 20 cm (length)

Step-by-step explanation:

Let width = w

Let length = 4w

Perimeter = 50

Perimeter formula for a rectangle = 2l + 2w

Plug in the variables (width and length)

2(w) + 2(4w) = 50

2w + 8w = 50

10w = 50

w = 5

Remember, recall that length = 4w

length = 4w

length = 4(5)

length = 20

Therefore, the dimensions of the rectangle are 5 by 20 cm

$15.40 per mile

step-by-step explanation:

you have to round up to 4 because 6 is over 5 so you have to round the 3 up to 4
