Half of a rectangle is a right angled triangle. Pythagoras! Hyp squared = 6 squared + 40 squared = 36 + 1600 = 1696 so Hypotenuse = sqrt 1696 = 41.18252

A rectangle doesn't have a hypotenuse.The diagonal of this one is sqrt(6,100) = 78.1025 (rounded)
By using the trigonometric ratios of Sine and Cosine. The diagonal forms the hypotenuse of a right angled triangle with the length and width of the rectangle forming the other two sides of the triangle - the adjacent and opposite sides to the angle. Then: sine = opposite/hypotenuse → opposite = hypotenuse x sine(angle) cosine = adjacent/hypotenuse → adjacent = hypotenuse x cosine(angle)

Area of rectangle = length x widthArea of rectangle = 0.3 m x 6 cm0.3 m = 30 cmArea of rectangle = 30 cm x 6 cmArea of rectangle = 180 cm2
The area of a rectangle can, indeed, equal 6 square units. The area of a rectangle is its length (l) times its width (w), and l x w = 6 can be 2 x 3 = 6 or 3 x 2 = 6 or 1 x 6 = 6 or 6 x 1 = 6 or 4 x 1 1/2 = 6 or any one of an infinite number of possibilities.
