Math Problem Statement
The area of a rectangular garden is 240m2. It's length is 20m. Find its perimeter
Solution
To find the perimeter of the rectangular garden, we first need to determine its width.
Given:
- Area of the garden:
- Length of the garden:
The area of a rectangle is calculated using the formula: Substituting the known values: To find the width, divide both sides by 20:
Now, the perimeter of a rectangle is given by the formula: Substituting the values for length and width:
Thus, the perimeter of the rectangular garden is .

Here are 5 related questions for further practice:
- If the length of the garden was increased by 5 meters, what would the new perimeter be?
- How would the perimeter change if the area remained the same, but the length was reduced to 15 meters?
- What is the length of a rectangle with an area of 240 square meters and a perimeter of 80 meters?
- How would you find the dimensions of a rectangle if only the perimeter and area were given?
- If the width was reduced by 2 meters, what would be the new area and perimeter?
Tip: When solving for one dimension of a rectangle given the area and the other dimension, remember that the area formula is the key equation to use.
