how many square feet are in a square yard?

Answer 1

there are three feet in a yard
therefore

it's 3x3 so it's 9 square feet = 1 square yard.

Answer 2

1 square Yard =9 Square Feet

Answer 3

Knowing the _law of exponents_ allows you to answer all of these question types without having to learn all kinds of strange formulas. Consider:

1 square yard.

This is a unit of area. I don't like working in areas, but there is a solution to my dislike. A square yard is defined as the area of a square one yard each side. This can be expressed:

= 1 (yd)^2

Now, if I express the 1 in the equation above as 1^2, I have

= 1^2 (yd)^2

and now the magic: the Law of Exponents: a^n * b^n = (a*b)^n

= (1 yd)^2.

This is more subtle than it appears. I am now dealing with lengths (of the sides of the square defining the area in question) instead of areas. Since we know that 1 yd = 3 ft, substitute:

= (3 ft)^2.

apply the law of exponents in reverse:

= 3^2 (ft^2)

do the arithmetic: 3^2 = 3*3 = 9

= 9 (ft^2)

= 9 square feet.

wolla, and the mystery is solved and explained. I am applying _dimensional analysis_, which minipulates the distance measurable quantities like (ft) and (yd).

Answer 4

There are 9 square feet in one square yard.

Answer 5

9

Answer 6

3feet= 1 yard

3^2 feet=1^2 feet

9 square feet= 1 square yard

Answer 7

1 square foot is equivalent to:
1/9 square yards

And...
A block 12 inches by 12 inches has a square foot area of 1 square foot.
144 square inches

Answer 8

9 because one yard has 3 feet. Three times three is nine. Nine square yard.

Answer 9

3 ft by 3 ft would be 9 square feet.

Answer 10
