Calculate 4 yd² to ft²

Step by step

The question

Question: change 4 yd² to square feet.

1 Change the length

This square is 1 yard on each side.

Its area is 1 square yard.

1 yard is 3 feet.

So each side is 3 feet long.

2 Change the area

So the square holds 3 rows of 3 small squares, each 1 square foot.

So 1 square yard is 3 feet times 3 feet.

3 times 3 is 9.

So 1 yd² = 9 ft².

Not 3: the 3 comes in twice.

3 Multiply

Each square yard is 9 square feet.

We have 4 of them, so we multiply: big unit to small unit.

Careful!

Times 3 only changes a length.

A square has two sides to change: times 3, and times 3 again.

4 times 9 is 36.

So 4 yd² = 36 ft².

4 Check

Let's check: go back the other way.

Divide by 9.

We get 4 square yards again.

So it is right!

Let's look back.

First: change the length.

Then: change the area.

Then: multiply.

Last: check.
