Question

the area of a right triangular region is 38.5cm square if one of the side containing right angle is 11 cm then find the other side

Answer 1

area of right angled triangle = 1/2 . base . height = 38.5


As one of side containing right angle is 11

let it be base

base = 11

So 1/2 × 11 × height= 38.5

11 × height = 77

height= 77/11= 7 cm
