Area = Length x Width so... 4 yards x 3 yards = 12 square yards
length = 12/3 = 4 yards
Multiplying length times width times height of an object measured in feet will give you that object's volume in cubic feet. Dividing that number by 27 will you give you the volume in cubic yards.

Think about it. 12 yards is about the length of three cars parked bumper-to-bumper. You'd need to ride AMAZINGLY slow to get that distance to last one hour.
"12 yards" is not an area. I must assume that you meant to saythat the area is 12 square yards.Then the length is 4 yards.
A square with a side length of 12 yards has an area of 144 square yards.
12 yards
It is probably 12 yards, since 12 feet is pretty short.
144 square yards
Area = Length x Width so... 4 yards x 3 yards = 12 square yards
a small couch (love seat) a bed
length = 12/3 = 4 yards
Length + width = half of perimeter so width = p/2 - length ie (22-12) 10 yards.
Using Pythagoras' theorem it is 20 yards in length.
In a piece of carpet that is 12 ft by 15 ft, there are 20 (twenty) square yards. Divide the length and width each by three to get the dimensions of 4 yards by 5 yards. multiply the length by the width to get an answer of 20 square yards.
Multiply width by length to get the area. The answer would be 216 square yards.
