Failranker (Question:107798.0)

Ye area nahi poochh raha median poochh raha h ye test series to Mene kharid li par aage nahi kharidunga or mere jitne bhi friend unse mana karoonga topranker ase hi nahi bante haram ki kamai kha rahe ho me ye sab expert se reh raha hoo ye to online liya h nahi to pese bhi vapis nikalva leta sudhar jao

Question:

The semi-perimeter of a right angled triangle ABC is 12 cm and the shortest median is 5 cm. What is area of the triangle which has the largest median of triangle ABC as its longest side?

Options:
A) \(\sqrt[]{73}\) cm2  
B) 10 cm2
C) 12 cm2  
D) None of these
Solution:
Ans: (c) 


Given: S = 12 cm & BP = 5 cm

∴ AP = PC = BP = 5 cm

∴ AC = 10 cm

 We know the ratio of Right triangle like (3:4:5) 

      then we assume the ratio, (6:8:10)

So, the other two sides = 8 cm, 6 cm

∴ Area of ∆QBC = \(\cfrac{1}{2}\times\) QB × BC = \(\cfrac{1}{2}\times\) 4 × 6 = 12 cm2
