Question

perimeter of a right angle triangle is 300 if its size sides are in the ratio of 5:12:13 then the area of the triangle is​

Answer 1

Answer:

Let, 1 side be  = 3x

  2 side be  = 5x

  3 side be  = 7x

According to question, 3x+5x+7x=300

⟹x=20

So, sides are 60,100,140

Area = s(s−a)(s−b)(s−c)

s=semi−perimeter 

 s=150,  a=60,  b=100,  c=140

Area=150(150−60)(150−100)(150−140)

⟹150(90)(50)(10)

⟹15003 m2

Answer 2

Answer:

5 Let the Sides of triangle be 5x, 122 and 13x..

Perimeter = a+b+c

= 150 = 5x+ 12x + 13x

150 = 30x

⇒ x = 150

30

z 50

First side. = 5x50

= 250m

Second side = 12x50
