Un granjero está cercando su terreno con alambre de púas el terreno tiene forma rectangular y sus medidas son de 37/3m de ancho y 42,8m de largo el número de vueltas fue de 3

He uses 330.8 meters of barbed wire.

Step-by-step explanation:

This can translate to:  

A farmer is fencing his lands with barbed wire. The land is rectangular with 37/3m of width and 42.8m of length, and he puts 3 loops of the wire.

I suppose we want to calculate the amount of wire used.

For each loop, the wire needed is equal to the perimeter of the rectangle, and the perimeter of the rectangle is equal to two times the length plus two times the width.

Then the perimeter is:

P = 2*37/3 m + 2*42.8 m = 110.27 m

And 3 times this amount is:

Wire used = 3*110.27 m = 330.8 m

1st integer x

2nd integer x+1

3rd integer x+2

4th integer x+3

x+x+1 +x+2+x+3 =74

combine like terms

4x+6 = 74

subtract 6 from each side

4x = 68

x = 17

the integers are 17,18,19,20
