Answer:
Area of the rectangular floor is [tex]252[/tex] square feet.
Step-by-step explanation:
First let's convert yards into feet.
1 yard = 3 foot
Length of the floor in feet:
[tex]7[/tex] yards = [tex]7*3[/tex] feet
=[tex]21[/tex] feet
Width of the floor in feet :
[tex]4[/tex] yards = [tex]4*3[/tex] feet
=[tex]12[/tex] feet
Area of a rectangle = Length * Width
Area of the rectangular floor = [tex]21*12[/tex]
=[tex]252[/tex] square feet
