The ratio òf the measurements of the three sides of a triangle is 3:7:5, and its perimeter is 156.8 meters. Find the measure of each side

Respuesta :

Let the sides of triangle are 3x, 7x and 5x

Perimeter = 3x+7x+5x = 156.8m
⇒ 15x = 156.8m
⇒ x = 156.8/15
⇒ x = 10.453m

3x = 10.453 x 3 = 31.36m
7x = 10.453 x 7 = 73.17m
5x = 10.453 x 5 = 52.27m

Three sides are: 31.36m, 73.17m and 52.27m
