Question

What’s the length of the hypotenuse of a right triangle if the length of one leg is 7 units and the length of the other leg is 14 units?

A. 10.72 units
B. 9.89 units
C. 13.75 units
D. 15.65 units

Answer 1

The answer is D. 15.65.

Explanation:

7^2+14^2

49+196=245

245 (squared) is 15.65

15.65*15.65= 244.9 rounded is 245

Answer 2

the length of hypotenuse comes out to be 15.65 units

Explanation:

given,

right angle triangle with one leg = 7 units

and another leg whose length is = 14 unit

to calculate the length of hypotenuse use Pythagoras theorem

H² = L² + B²

H =
`√(L^2 + B^2)`

H =
`√(14^2 + 7^2)`

H =
`√(245)`

H = 15.65 units

hence, the length of hypotenuse comes out to be 15.65 units
