Question

How many yards are in a square mile?

Answer 1

Hint: We first find the relation between mile and yard. The measurement is common in measurement units of length. We find the relation as 1 mile being equal to 1760 yards. We use the unitary system and the concept of area from length, to find the yards for 1 square mile.

Complete answer:
We need to convert the length by changing its unit from mile to yard and then we need to take the square for area conversion.
We find the relation between mile and yard 1 mile being equal to 1760 yards.
We already have that in the unitary system. The unitary method is a method in which we find the value of a unit and then the value of a required number of units. The unitary method is also used to find the value of a single unit from a given multiple.
We take the square value of both the units and the conversion rate to find the square yards present in a square mile. We take the square of 1760.
Therefore, 1 square mile is equal to ${{1760}^{2}}=3097600$ square yards.
Therefore, 1 square mile is equivalent to $3097600$ square yards.

Note:
The mile and yard are units of measurement for length in both the US customary units and the metric systems of measurement. This unit is used in the normal or common measurement units. It can also be changed to other common measurement units using the relation in the metric system. But we need to remember that square miles and square miles are units of area.
