Question

The sides of a triangle are in the ratio 6 : 7 : 8 and its perimeter is 420 cm. find its area using

Heron’s formula.​

Answer 1

Step-by-step explanation:

Given, perimeter of a triangular field is 420 m and its sides are in the ratio 6:7:8. Let sides of a triangular field be a=6x, b=7x and c=8x. and c=8×20=160m. Hence, the area of triangular field is 2100√15m2.

Answer 2

Answer:

side of triangle=x=6x

6x, 7x, 8x=420cm

21x=420cm

20cm
