Question

the perimeter of the triangular field is 400cm and its sides are in the ratio of 5:7:8 find the area of the triangular field​

Answer 1

Step-by-step explanation:

let the ratio be=5x ,7xand 8x

perimeter of triangle= 400 cm

5x+7x+8x=400

20x=400

x=400/20

x=20

1st side =5x=5*20=100

2nd side = 7x=7*20=140

3rd side=8x= 8*20=160

The three sides of the triangle are 100,140&160.
