Afarmer wishes to fence a rectangular area behind his barn. the barn forms one end of the rectangle and the length of the rectangle is three times the width. how many linear feet of fence must he buy if the perimeter of the rectangle is 320 feet

280 feet

Step-by-step explanation:

Let width of rectangle be x

Since we are given that  the length of the rectangle is three times the width.

⇒ Length = 3x

Now, perimeter of rectangle =

Perimeter of rectangular area:

Thus the width of the rectangular area is 40 feet .

Length = 3x= 40*3=120 feet.

Since we are given that The barn forms one end of the rectangle

⇒

⇒        

⇒  

⇒        

Hence he must buy 280 feet of fence to form barn if the perimeter of the rectangle is 320 feet                            

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
