The length of a field is three times its width. If the perimeter is 64 m, what is the width of the field?

P = 2L + 2W

64 = 2(3W) + 2W

64 = 8W

? = W

thanks

You're welcome.

To find the width of the field, we need to set up an equation using the given information.

Let's assume the width of the field is "w" meters.

According to the given information, the length of the field is three times its width, which means the length would be 3w meters.

The perimeter of a rectangle is calculated by adding up the lengths of all four sides. For a rectangle, the formula for the perimeter (P) is P = 2(length + width).

In this case, the length is 3w and the width is w. Therefore, the equation for the perimeter is:

2(3w + w) = 64

Simplifying the equation:
2(4w) = 64
8w = 64
w = 64/8
w = 8

Hence, the width of the field is 8 meters.
