Hypotenuse

Calculate the length of the hypotenuse of a right triangle if the length of one leg is 4 cm and its content area is 16 square centimeters.

Result

c =  8.944 cm

Solution:

a=4 S=16 S=ab/2 b=2⋅ S/a=2⋅ 16/4=8 c=a2+b2=42+82≐4 5≐8.9443≐8.944 cma=4 \ \\ S=16 \ \\ S=ab/2 \ \\ b=2 \cdot \ S/a=2 \cdot \ 16/4=8 \ \\ c=\sqrt{ a^2+b^2 }=\sqrt{ 4^2+8^2 } \doteq 4 \ \sqrt{ 5 } \doteq 8.9443 \doteq 8.944 \ \text{cm}
