50 squared = 2500 40 squared = 1600 add these two together to get 4100 so your answer is 50 and 40

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

area = pi x diameter squared/4 = 400 pi diameter squared = 4 x 400 x pi/pi = 1600 diameter = sqrt 1600 = 40

1600

The easy answer: Yes. To go in depth, the pythagorean theorem is a^2+b^2=c^2. C is always the longest side, or hypotenuse, so you would replace c with 40. A and B can be in any order, so let's replace a with 24 and b with 32. A Squared=24 Squared=576 B Squared=32 Squared=1024 C Squared=40 Squared=1600 Now to test it: 576+1024=1600 1600=1600 So yes, it is a pythagorean triple. * * * * * There is a simpler method. 3-4-5 is a well known Pythagorean triple. Therefore, any multiple of the triple is also a Pythagorean triple. 24-32-40 are 8 times the corresponding numbers and so they form a Pythagorean triple.

The hypothnuse is from the Pythagorean theorem: side squared + side squared = hypothenuse squared So 9^2 + 40^2 = 81 + 1600 = 1681 hypothenuse = square root 1681 = 41 feet
