The perimeter of a rectangle is 34 units, its width is 6.5 units. Write an equation to determine the length (l) of the rectangle.

Solution:

Given, perimeter of a rectangle = 34 units.

Width = 6.5 units

We have to write an equation for the length of the rectangle.

Perimeter = 2(length + width)

length + width = perimeter/2

length = (perimeter/2) - width

So, length = (34/2) - 6.5

length = 17 - 6.5

length = 10.5 units

Therefore, an equation for the length of the rectangle is length = (perimeter/2) - width.

The perimeter of a rectangle is 34 units, its width is 6.5 units. Write an equation to determine the length (l) of the rectangle.

Summary:

The perimeter of a rectangle is 34 units, its width is 6.5 units. An equation to determine the length (l) of the rectangle is length = (perimeter/2) - width.
