Question

iii) If the sides of the triangle in another model are in the ratio 3:5:7 and its perimeter is 300 m, then the sides of the triangle are​

Answer 1

Step-by-step explanation:

sum of the ratio = 3+5+7

= 15

the perimeter of the triangle = 300 m

then, each side of the triangle measures = (300/15) m

= 20 m therefore ,

sides of the triangle measure = (20*3)m

= 60 m

= (20*5)m

= 100m

= (20*7)

= 140m

hence, the sides of the triangles are 60,100,140 respectively
