The hypotenuse of a right-angled triangle 10 cm and its area is 24 cm^2. If the shorts side is halved and the longer side is double, the new hypotenuse becomes

√245 cm
√255 cm
√265 cm
√275 cm

Correct Answer: √265 cm

Hypotenuse = 10cm

Let the other 2 perpendicular sides be a and b

Area ½ a*b = 24

So a*b = 48 cm^2
