Question

The three sides of a triangle are n, 4n+1, and 5n−8. If the perimeter of the triangle is 93cm, what is the length of each side?

Answer 1

Answer:

ok

thank you

Step-by-step explanation:

Sides of triangle= n, 3n-6,4n-11

Perimeter= 39 inches

Side+Side+Side= Perimeter

or, n + (3n-6)+(4n-11)=39

or, n+3n-6+4n-11=39

or, 8n=39+6+11

or, 8n=56

or, n=56/8

or, n=7

Therefore, length of each side:-

n= 7 inches

3n-6=(3×7-6) inches

=15 inches

4n-11=(4×8-11)

=21 inches
