Lance is building a rectangular fence for his chickens. He wants the length to be three times the width and he has 80 feet of fencing. What is the largest possible length? Write an equation and solve.

A) 8w=80; 10
B) 4w=80; 20
C) 8w=80; 30
D) 4w=80; 15

C) 8w = 80;30  

This is because it is a rectangle and 30ft +30ft =60ft length.

The question asks to make the fence as large as possible  fencing overall is same ratio as D but more for length.

The new equation could be for total width both sides;

           9^2 -1w = 5

               81-1w = 5

                     w = 80/5

                     w = 16ft

i think the answer is b)

step-by-step explanation:

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
