hello
let's assume the room is a rectangular room and we can use the formula for area of a rectangle to find the total area
we can convert the dimensions from feet to yards
[tex]\begin{gathered} 1yd=3ft \\ \text{length =} \\ 1yd=3ft \\ \text{x yd}=15 \\ x=\frac{15\times1}{3} \\ x=5ft \\ \text{width} \\ 1yd=3ft \\ z\text{ yd= 12ft} \\ z=\frac{12\times1}{3} \\ z=4yd \end{gathered}[/tex]now we've established that the length and width of the room is 5yd and 4yd respectively
[tex]\begin{gathered} \text{area}=l\times w \\ \text{area}=5\times4 \\ \text{area}=20yd^2 \end{gathered}[/tex]the square yard required is 20yd^2
