Question

Sides of a triangle are in the ratio 3:4:5 and it's perimeter is 360m, find the area of the triangle​

Answer 1

Answer:

nearly 120√3

Step-by-step explanation:

let let the sides of triangle be x

then size of triangle=3x ,4x and 5x

since parameter=360m

so, 3 x+ 4 x + 5 x = 360

12x = 360

x=30

now you manage

Answer 2

Answer:

Perimeter of triangle= sum of all sides

Side 1= 3x

Side 2= 4x

Side 3=5x

Now, perimeter of triangle= 3x+4x+5x

360 = 12x

Therefore, x is 30 (360/12).

Now to find the area of triangle,

Area of triangle= 1/2 base × height

Base is (3x)= 90

Height is (4x)= 120

Area = 1/2×90×120

Therefore area of this triangle is 5400 m^2

Note: "^2" this symbol means square.
