(a) 270 Square feet

(b) 30 Square Yard.

Step-by-step explanation:

Tina's rectangular living-room floor measures 15 feet by 18 feet.

Length=18 feet

Breadth = 15 feet

Area of a Rectangle = Length X Breadth

(a) Area of the Room = 15 X 18 = 270 Square feet

Tina will need 270 Square feet of carpet to cover the entire room.

(b) 1 Yard = 3 Feet

(1 X 1) Square Yard = (3 X 3) Square Feet

1 Square Yard = 9 Square Feet

If Tina needs 270 Square feet of carpet

9 Square Feet = 1 Square Yard

270 Square feet = (270/9) Square Yard

=30 Square Yard.

90 square yards will be needed
