The area of rectangle is : 18.0
20cm squared
A rounded rectangle.
Well, you know that in order to classify a shape as a rectangle all of the sides have to be congruent or 90 degrees. If you draw the diagonal of that rectangle, you come up with two right triangles. So you can use the Pythagorean theorem (a squared+b squared=c squared) to find out the diagonal. Ex: If the length=4, and width=3, then diagonal=5, because 4 squared+3 squared=5 squared.
Area of a rectangle = length * width = 72 feet-squared
15 squared is exactly 225.
ratio is 18 to 6 which is 3 to 1.
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

To find the length of a diagonal in a rectangle, use the Pythagorean method. Diagonal length = square root(length squared + height squared).
