given the length of 9.850mtrs,and the width of 8.650mtrs,how do I calculate the length of the diagonal.?

Question

I don't have any tools to hand to do it physically,is there a formula.

Answer 1

Pythagorean Theorem

In a right angled triangle, the square of the hypotenuse equals the sum of the square of the other two sides.

Therefore
9.850^2+8.650^2=171.845
171.845 rooted = 13.108966397

Your diagonal will be 13.11 Mtrs

Answer 2

Assuming the two sides are at right angles to each other, you could use Pythagorus' theorem.

You may have heard in rumour that for a right angled triangle,
"the square on the hypotenuse is equal to the sum of the squares on the other two sides"

That's mathsey shorthand for: Multiply the length by itself, multiply the width by itself, add these two together, take the square root to get the diagonal.
.._____________
\/ (L*L) + (W*W) = D

Not sure if this font does it justice, but I've tried to illustrate the wonky tick which is the symbol for square root.

Best of luck.

Answer 3

Yes. The formula is a^2 + b^2 = c^2, where a and b are the sides and c is the diagonal. this is called the Pythagorean Theorem.

Answer 4

use a casio calculator, press pol( then type in the length 9. 850mtrs
next type in a , followed by the width 8.65mtrs
finally type in a ) press equals to get the answer 13.1089664mtrs
the display should read pol(9.85,8.650)
there is a bonus, press rcl then tan to get one of the angles
or try 9.850 squared + 8.65 squared then square root

Answer 5

(height x height) + (width x width) = (diagonal x diagonal)

assuming a right angle triangle 90 degrees

or draw to scale on a piece of paper. 9.85 mtrs 9.85 centimeters

Answer 6

pythagoras

9.85^2 + 8.65^2 = Diagonal^2

=13.11mtrs

Answer 7

Easy enough by Pythagoras if you have a right-angle, but you don't actually say as much in your question.
Could you elaborate?

Answer 8

Absolutely great answers above!

Answer 9

The hypotenuse is what your after.

a² + b² = c²
