How can you use negative numbers to represent real-world problems

Hi , basically when we want to use negative numbers in real world problems , we should always put words like decrease , drops , less , because those words describe an explicit situation that describes subtraction , for example Ana is playing soccer with her friends , her score is less than 0 because she has been trying to mark a goal but she is unable to do it . The score of Ana is -5 , the score of her friend is -2 .

If 6m by 15m is a pond ,is 40m would be enough for fencing the pond

Veseljchak [2.6K]

If the pond were a rectangle, then:
length=15 m
width=6 m

We would have to calculate the perimeter of this rectangle.
Perimeter of a rectangle=2(length)+2(width)

Perimeter of this rectangle=2(15 m)+2(6 m)=30 m+12 m=42 m

We need 42 m and I only have 40 m, therefore, it would not be enough for fencing the pond.
