Answer:
She needs 3 gallon of paint for fencing.
Step-by-step explanation:
Given,
The fencing will enclose a rectangular yard that is 3 yards long and 2 yards wide,
⇒ Total fencing = Perimeter of the rectangle that is 3 yards long and 2 yards wide
Since, the perimeter of a rectangle = 2 ( length + width )
⇒ Total fencing = 2 ( 3 + 2 ) = 2(5) = 10 yards,
Also, 1 yards = 3 feet,
⇒ Total fencing = 3 × 10 = 30 feet.
According to the question,
She needs 1 gallon of paint for each 10 feet of fencing,
Thus, the quantity of paint needed for fencing = Total paint needed for 30 feet
= 3 × Total paint needed for each 10 feet
= 3 × 1 gallon
= 3 gallon,
Hence, she needs 3 gallon of paint for fencing.
