Question

the perimeter of a triangle is 900 m .Find the lenght of its sides which are in the ratio 5 is to 7 is to 8 .
​

Answer 1

Answer:

Let the sides be x m

5x+7x+8x=900

20x=900

x=1/45m

Answer 2

Answer:

let the ratio be 5x 7x 8x

perimeter = 5x +7x +8x

900 = 20x

900/20= x

45= x

sides of triangle = 5x = 45× 5= 225m

= 7x= 7 ×45= 315m

= 8x = 8×45= 360m
