How much carpet is needed to cover 2 rooms, one of which is 12 ft by 6 ft and the other 10 ft by 8 ft?

  152 square feet

Step-by-step explanation:

The area of a rectangle is the product of its length and width. The total area of carpet required is the sum of the areas of the two rooms:

  carpet area = (12 ft)(6 ft) +(10 ft)(80 ft) = 72 ft^2 +80 ft^2

  carpet area = 152 ft^2

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
