Question

The sides of a triangle are in the ratio 5 : 12 : 13 and its perimeter is
150 m. Find the area of the triangle.​

Answer 1

Step-by-step explanation:

• let sides are 5x and 12x and 13x 5x+12x+13x=150m 30x=150m. x=5 first

Answer 2

Answer:

5y+12y+13y=150m

30y = 150m

y=150/30

y=5

5y=25

12y=60

13y=65

USING HEROS FORMULA

√S(S-A)(S-B)(S-C)

S=A+B+C/2

S=75CM

SOLUTION

√75(75-25)(75-60)(75-65)

√75(50)(15)(10)

√5*3*5(10*5)(5*3)(10)

5*5*3*10

Area=750m2
