To make a rectangle using a 6-piece tangram, you need to arrange the pieces in a specific way. First, place two large triangles together to form a square. Then, position the two small triangles on top of the square to create a larger square. Finally, fit the two parallelograms on the sides to complete the rectangle shape. This arrangement utilizes all six pieces of the tangram to form a rectangle.
Using Pythagoras: 322+362 = 2320 and the square root of this is the length of the diagonal
To find the area of a rectangle, you need to know the formula: Area = length x width. Given that the perimeter is 72m and the width is 16m, we can calculate the length by using the formula for perimeter of a rectangle: Perimeter = 2(length + width). Substituting the values we have, 72 = 2(length + 16), which simplifies to length + 16 = 36. Therefore, the length of the rectangle is 20m. Finally, the area of the rectangle is 20m x 16m = 320 square meters.
