Question

the sides if a triangular field are in the ratio 5:7:8 and its perimeter is 400m ​

Answer 1

Answer:

:let the sides be =5x,7x,8x

perimeter of triangle =

5x + 7x + 8x =400 m

12x + 8x = 400

20x = 400

x =400/20

 = 20

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

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

2rd side = 8x = 8 * 20 = 160

The three sides of triangle are 100,140,160

Answer 2

Answer:

first of all you have to type the whole question

Step-by-step explanation:

let all sides of triangle be x

First side=5x

Second side=7x

Third side=8x

Perimeter of triangle- a+b+c

400-5x+7x+8x

400-20x

x=400/20

x=20

Out value of x =20

5x=5×20=100

7x=7×20=140

8x=8×20=160

These are the sides of the triangle...✨
