Answer: 20 yrd²
Step-by-step 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:
![12ft\cdot(1yrd)/(3ft)=4yrd](https://img.qammunity.org/2023/formulas/mathematics/high-school/669nnxj1f95iyp7g67l2nj7l5yd7fmsrcj.png)
![15ft\cdot(1yrd)/(3ft)=5yrd](https://img.qammunity.org/2023/formulas/mathematics/high-school/jeirzmnktlywcmv03i3eqlipucwe3z2c1o.png)
Finally, we have to calculate the area A we will cover by multiplying the dimensions given:
