A rectangular tablecloth is 2.5 m long. Trim is to be sewn around the perimeter of the cloth but there is not enough. What decrase in width will make the perimeter 0.4m shorter if the length remains the same?

The shorter side of a rectangle is 20 m. Decreasing the longer side by 30 cm reduces the perimeter by one half. How long are the longer sides of the original rectangle? Explain the reasoning.

One side of an isosceles triangle is 15 cm shorter than the other 2 sides. The perimeter is 120 cm. How long are the sides of the triangle?

Draw a hexagon and a rectangle that have the same perimeter as the triangle.
