Question

If the legs of a right angle are 3 feet and 4 feet, the length of the hypotenuse is how many feet

Answer 1

Hi there!

• Base, b = 3 ft
• Perpendicular, p = 4 ft.

According t' Pythagoras theorem :-

h = $\sqrt {b^2 + p^2}$

h = $\sqrt {3^2 + 4^2}$

h = $\sqrt {9 + 16}$

h = $\sqrt {25}$ = 5 ft.

Hence,
Th required length of Hypotenuse, h = 5 ft.

~ Hope it helps!
