Question

Deon has 26 meters of wire fencing to make a rectangular pen for his two show lambs. He has learned that each lamb should have 20m^2 of space. Does he have enough fencing for an area of 40m^2? Use a table to determine your answer.

Answer 1

Answer:yes but only when using length=8m and width=5m.

Explanation

Table that shows some measurments for length and width to result in 40 m^2:

1*40 results in fencing of 2*(1+40) =82

2*20 results in fencing of 2*(2+20) =44

4*10 results in fencing of 2*(4+10) =28

5*8 results in fencing of 2*(5+8) =26
