How do you work out the diagonals of a 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.
What is the perimeter of a rectangle with one side 8cm if it has an aera of 40cm?
26cm
What is the area of a rectangle if the width is 40cm and the length is 2 meters?
80 meters
How many rectilinear shapes can you draw as if you have a perimeter of 40cm?
35
What are the possible lengths and widths of a rectangle with a perimeter of 40cm?
One possibility is 15 x 5 (therefore perimeter is 15 x 15 x 5 x 5 = 40cm).
The diagonal of a rectangle is 50cm if the length of a rectangle is 40cm what is the width?

it is possible to draw a square that is a rectangle?
What is the area of a rectangle 2cm by 9cm?
The area of rectangle is : 18.0
What is the area of a regular hexagon with side length of 40cm?
To find the area of a regular hexagon with side length of 40cm, consider that since it is regular, then it consists of 6 equilateral triangles of side 40cm. Half of each of those triangles is a right triangle. By the pythagorean theorem, we know that if the hypotenuse is 40cm, and one side is 20cm, then the other side is the square root of (40cm squared - 20cm squared) or about 34.64cm. That makes the area of each of those 12 right triangle to be about 692.8cm, so the total area of the hexagon is about 8313.8cm.

What is the perimeter of a rectangle 40cm and 8cm sides?
2*(40 + 8) = 2*48 = 96 cm.
Find the area of a rectangle that is 20cm by 40cm?
Well, darling, to find the area of a rectangle, you simply multiply the length by the width. In this case, 20cm x 40cm gives you a grand total of 800 square centimeters. Voila, you've got your area!
