Question

How many feet are in \[5\] yards?

Answer 1

Hint: To solve this question we need to know the relationship between both the units of length, feet, and yard. Also, this question is solved using the unitary method in which we first find the value of a single unit, and then the value of a particular value is found by multiplying by the single unit. The relationship between feet and yard is
$1\,yard=3\,foot$
i.e. $ft=yd*3.0000$
where $ft$ is the length in feet and $yd$ is the length in yards.

Complete step by step solution:
Let $x$ be the number of feet in $5$yards.
We know,
$1\,yard=3\,foot$
Then by using unitary method:
$5\,yard=5*1yard$
$5\,yard=5*3feet$
Therefore ,we can write-
Number of feet in 5 yards,$x=5*3$feet
=>$x=15$ feet
=> $5\,yards=15\,feet$

Therefore , there are 15 feet in 5 yards.

Note: A yard is a unit of length equal to \[3\] feet or $91.44$ centimeters, originally taken to be the average length of a stride. The foot is a unit of length used in the imperial and United States customary measurement systems, representing \[1/3\] of a yard, and is subdivided into \[12\] inches. Feet and yard are both common units of length and yard are used for linear measurement in English-speaking countries, though the standard international unit of length is meter. All these units of length are related to each other using formulae.
