The perimeter of a triangle is 420m the ratio of the sides are6:7:8 then find the area of the triangle?

to find :

find the area of the triangle?

solution :

• Given, perimeter of a triangular field is 420 m and its sides are in the ratio 6:7:8.

• a triangular field be a = = 7x and c = 8x. 6x, b

• Perimeter of a triangular field, 2s = a + b +

• c⇒ 420= 6x + 7x + 8x ⇒ 420 = 21x ⇒ x = 420/21 = 20 m.
