Question

American football is played on a $100\mathrm{yd}-$long field, excluding the end zones. How long is the field in meters? (Assume that $1\text{m}=3.281\text{ft}$)

Answer 1

Determining the length of the field in meters.

Given data,

American football field length $l_1=100\text{yd}$.

Finding the length $l_2$ of the field in meters.

$1\text{m}=3.281\text{ft}$

We know that

$$\begin{gathered} \Rightarrow 1\text{yd}=3\text{ft} \\ \therefore 100\text{yd}=300\text{ft} \end{gathered}$$

Now, we can convert it into the desired unit of meter.

$$\begin{gathered} l_2=300\text{ft} \\ =\frac{1}{3.281}\times 300\text{m} \\ =91.44\text{m} \end{gathered}$$

Hence, the length of the field is $91.44\text{m}$.
