18.the total fencing around a square field is 80 yards. the field has an area of how many square yards?

Hi there! The answer is 400 square yards.

When the total fencing around a square field is 80 yards, that means that the fencing on one side of the square field is 80 / 4 = 20 yards (Since a square field has 4 sides which are equally as long as every other side).

When the side of the field is 20 yards, the area (which is width * length) equals 20 yards * 20 yards = 400 square yards.

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
