Question

the sides of a triangle are in the ratio 7:5:8. if its permeter is 440cm , find the sides of the triangle

Answer 1

let the ratios be 7x + 5x + 8x
sum= 20x

therefore:
20x= 440
x= 440/20
= 22.
Therefore he sides are : 7*22 ,5*22,8*22=≥ 154 ,120 ,176 are the sides.

Answer 2

Answer:

Perimeter of triangle=440

Let the side of triangle be x

Measures of the side of triangle in ratio=7:5:8

=7x:5x:8x

Perimeter of triangle=7x +5x+8x

440= 20x

20/440=x

22=x

∆ 7x=7*22

= 154

∆ 5x= 5*22

= 110

∆ 8x=8*22

= 176
