In the right triangle, the ratio of the legs is 1: If the area of the triangle is 25 square units, what is the length of the hypotenuse?

A √5

B 10√3

C 25√5

D 5√3

Correct Answer: Option E

suppose, legs are x and 2x here, 1/2 x X x 2X=25 or,x2=25 :.x=5 so , legs are 5 and 10 we know, (hypotenuse)2=52+102 or, hypotenuse=5√5
