Question

Draw a rectangle of perimeter 30 centimetres and
lengths of sides in the ratio 1:2. Draw two more
rectangles of the same perimeter, with lengths of sides
in the ratio 2:3 and 3:7. Compute the areas of all
three rectangles.​

Answer 1

Answer:

To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results.
