Question

the length of the right triangle are equal the square of the hypotenuse is 900 cm2 . find the lenght of each side.

Answer 1

Let the length of the side of right angle triangle is x cm.

Using Pythagoras theorem

${x}^{2} + {x}^{2} = 900 \\ 2 {x}^{2} = 900 \\ {x}^{2} = \frac{900}{2} \\ {x}^{2} = 450 \\ x = \sqrt{450} \\ x = 21.21$
So the length of each sides are 21.21 cm, 21
21 cm and 30 cm.
