Jules owns a square plot of land that measures 30 yards on each side. He plans to divide the land in half by building a fence, a
s shown by the dotted line below. How many yards of fencing will Jules need?
1 answer:
We are asked to solve and determine the total yards that Jules needed to fence his land. Initially, we have an original square lot area of 30 yards by 30 yards. Then it is divided by two and we need to compute for the new perimeter of the land so that we will know the total fence that we need.The solution for the perimeter is shown below:
Perimeter = 30 +15 + 15 + 30 + 15+ 15 + 30 (the middle)
Perimeter = 150 yards
Jules needs 150 yards to fence his land.
Perimeter = 30 +15 + 15 + 30 + 15+ 15 + 30 (the middle)
Perimeter = 150 yards
Jules needs 150 yards to fence his land.

B. The total area painted is 864; they must buy two cans of paint.
Step-by-step explanation:
Step 1:
A rectangle's area can be calculated by multiplying its length and its width. The wall is made up of 5 different types of rectangular walls. All walls are 8 feet tall but the length varies.
Step 2:
The area of the 20 feet long wall =
The area of the 10 feet long wall =
The area of the 5 feet long wall =
The area of the 4 feet long wall =
The area of the 15 feet long wall =
The area of all the walls = 432 square feet.
Since there are two sides for every wall, total area = square feet.
Step 3:
If one paint can covers 500 square feet,
the number of cans required to paint 864 square feet = cans.
so 2 paint cans are needed to paint 864 square feet which is option B.
