Let the lengths, in cm, of the sides of the right-angled triangle be and , where is the length of the hypotenuse. The area of the right-angled triangle is . We are told that and . By Pythagoras’ Theorem, so . Hence . Therefore . So . Hence , so . Therefore the area of the ...
To find the length of the hypotenuse in right triangle ABC with legs a = 6 cm and b = 4.5 cm, we can use the Pythagorean theorem. The theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the sq
