Question

15. The sides of a right angled triangle are in the ratio 5:12:13 and its perimeter is 120 units
then, the sides are
(A) 25, 36,59 (B) 10,24,26 (C) 36, 39, 45 (D) 20,48,52​

Answer 1

let the sides are 5x , 12x and 13x

according to the question

perimeter = 5x+ 12x+ 13x

120 = 30x

x= 120/30

x= 4

hence the sides are 5x = 20unit , 12x= 48unit and 13x= 52 unit
