Arectangle has a width of 46 centimeters and a perimeter of 208 centimeters. what is the rectangle's length?

To find the perimeter of a rectangle, you need to add all of the side lengths together.

We are given that the width of one side is 46 cm. We also know that the perimeter is 208 cm.

2 sides of the rectangle will be 46 cm and the other 2 will be x (we don't know these as of now, replace it with x)

46+46=92

This is your equation to solve:

92+2x=208

You're trying to get x by itself, so you need to subtract 92 from each side.

This will be your equation after subtracting 92:

2x=116

Now, all you need to do is divide by 2 on each side to get x by itself.

x=58

This means that the rectangle's length is 58 cm.

To check this, add all of your side lengths together:

46+46+58+58=208

If you have any questions, don't hesitate to ask!

the answer is 62

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
