I would list all the factors of 480 (as pairs of numbers whose product is 480).
Then find two pairs of numbers (L1,W1 and L2,W2) satisfying these properties.
(It won't take long, since there are at most sqrt(480) (rounded down) pairs of numbers whose product is 480, ie. just try the numbers 1,2,3,...,21.)
Hope that helps!

Information about a rectangle?
There are plenty of information you can learn about rectangles. You can learn about their angles, their widths and lengths, as well as their volumes.
Can two rectangles have the same area but different lengths and widths?
Yes. Consider a 2 x 6 and a 3 x 4
A group of sudents are finding the perimeters of rectangles whose lengths and widths are whole numbers they notice that all the perimeters are not even numbers is this always true?
No, take the rectangle that is 4x6. The perimeter is 20 which is even.

What is the perimeter of a 3.5Cm wide square?
14cm. Since squares have the same widths and lengths. A 3.5cm wide square will have 3.5cm X 4 = 14cm of perimeter.
How do you find the height for a rectangular prism with the giving lengths and widths?
You cannot. The lengths and widths are not sufficient information to determine the height.

How many different rectangles can have an area of 24 square inches if their lengths and widths are whole numbers?
4
Can two rectangles have the same area but different lengths and widths?
Yes. Consider a 2 x 6 and a 3 x 4
What is the length of the sides of a rectangle that has a perimeter of .875?
You can't tell the dimensions from the perimeter. There are an infinite number of different rectangles, all with different lengths and widths, that all have the same perimeter.
What is the Difference between rectangle and rhombus?
A rectangle has 2 equal widths and 2 equal lengths whereas a rhombus has 4 equal widths but they are both 4 sided quadrilaterals.
How do you find the widths of a rectangle with the lengths?
You can't find the widths of a rectangle with the lengths because the widths can be anything lower than the lengths. Like if your rectangle had a length of 7 the width can be 6, 5, 4, 3, 2, and so on.
A group of sudents are finding the perimeters of rectangles whose lengths and widths are whole numbers they notice that all the perimeters are not even numbers is this always true?
No, take the rectangle that is 4x6. The perimeter is 20 which is even.
What is a parallelogram with 4 right angles with different lenghts and widths?

How do you determine the area and perimeter of geometric figures?
Area is length x width. Meanwhile Perimeter is the addition of all the lengths and widths of the entire geometric polygon.
What is the perimeter of 5000 acres in meters?
You can't tell the linear dimensions from knowing only the area. There are an infinite number of shapes that all have the same area. Even if you consider only rectangles, there are still an infinite number of different rectangles, all with different lengths and widths, that all have areas of 5,000 acres.
When doubling the lengths and widths of a rectangle the angle measures will do what?
stay the same
