Answer: 20 yrd²
Explanation
Given
• Bedroom measures: 12 ft by 15 ft
Procedure
To know how many sq yards we have to buy, first we have to convert 12 ft and 15 ft to yards, considering that 1 yrd = 3ft:
[tex]12ft\cdot\frac{1yrd}{3ft}=4yrd[/tex][tex]15ft\cdot\frac{1yrd}{3ft}=5yrd[/tex]Finally, we have to calculate the area A we will cover by multiplying the dimensions given:
[tex]A=b\times h[/tex][tex]A=4\times5=20yrd^2[/tex]
