Answer:

perimeter: 22 1/30 m
area: 29 m²

Step-by-step explanation:

The perimeter is given by the formula ...

P = 2(L+W)

P = 2(4 7/20 +6 2/3) = 2(10 +61/60) = 2(11 1/60)

P = 22 1/30 . . . . meters

The area is given by the formula ...

A = LW

A = (4 7/20)(6 2/3) = (87/20)(20/3) = 87/3 = 29 . . . . square meters

The perimeter is 22 1/30 meters; the area is 29 square meters.

Which operations is the following set closed under: {... , -3, -1, 1, 3, ...}?

Ganezh [65]

Not addition, since $-1+1=0$ and 0 doesn't belong to the set.

Not subtraction, since $1-1=0$ .

It is closed under multiplication. The set appears to contain all non-zero multiples of 3.

Not division, since dividing some of the numbers results in rationals which do not belong to the set.

What other operations are you supposed to consider?
