Answer 1

1 yard is 3 feet

3 yards times 3 = 9 feet

2 yards times 3= 6 feet

9+6= 15ft

elena will need 2 gallons of paint

Answer 2

The answer is 3 gallons of paint.

Explanation:

Elena is painting a fence she has already determined that she needs 1 gallon of paint total for each 10 feet of fencing.

The dimensions of yard are = 3 yards by 2 yards.

We will convert the yards in feet.

1 yard = 3 feet

So, the dimensions are = 9 feet by 6 feet

Perimeter will be =
`(2*9)+(2*6)`

=
`18+12=30` feet

Now its given that, 1 gallon paints 10 feet of fencing.

So, to paint 30 feet of fence, the paint required will be =
`30/10=3` gallons.

Therefore, the answer is 3 gallons of paint.
