What is width of rectangle with length 40 meters and perimeter 120 meters?
To find the perimeter of the rectangle you add up all the sides. There are two lengths and widths for every rectangle, so you know the length is 40 meters x 2 = 80 meters. Perimeter is the total length of all the sides so you just minus 120 from the two lengths which is 80. So the width is 40, divide 2 (2 widths) = 20 meters. Width = 20 meters OR if they're asking for widthS then it'll be 40 meters, but they're not.
What is the width and length of a rectangle if the perimeter is 50 and the length is 5 cm more than the width?
Perimeter = 2 lengths and 2 widths In your case length + width = 25cm If length is 5cm more than width then length = 15cm and width = 10cm
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.
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.
What is the length of a rectangular lot that has a perimeter of 730 m and a width of 75 m?
The perimeter of a rectangle is the sum of its sides, so 2 lengths plus to widths: P = 2l + 2w We know P and w: 730 = 2l + 2(75) 730 = 2l + 150 Subtract 150 from both sides: 580 = 2l Divide both sides by 2: 290 = l The length is 290 meters.
