Question

* The length of a rectangular

field is 20m longer than width.
Find an expression for the perimet
perimeter of the field in terms of
its length.

Answer 1

The perimeter of a rectangular field can be calculated using the formula: Perimeter = 4w + 40, where 'w' is the width of the field.

Step-by-step explanation:

The perimeter of a rectangular field is the sum of all its sides. Let's assume that the width of the field is represented by the variable 'w'. According to the given information, the length of the field is 20m longer than the width, so it can be represented as 'w + 20'.

The perimeter is calculated by adding the length of all four sides. For a rectangle, two opposite sides have equal lengths. Therefore, the perimeter is given by:

Perimeter = 2w + 2(w + 20)
This can be simplified as:
Perimeter = 4w + 40
