Answer: 168

Step-by-step explanation:

Given: The dimensions of the garden is 33 ft by 39 ft.

Since the garden has a path around it that is 3 ft wide.

Then, the new dimensions of the garden with path will be (33+2(3)) ft by (39+2(3)) ft or 39 ft by 45 ft.

The perimeter of rectangle is given by :-

P=2(l+b)\\\\\Rightarrow\ P=2(39+45)\\\\\Rightarrow\ P=2(84)\\\\\Rightarrow\ P=168\ feet

Hence, the Joe need 168 feet fencing material to enclose the garden and path.

Lady bird [3.3K]

Answer:

500 bricks.

Step-by-step explanation:

There are 250 bricks used to build a wall that is 20 feet high how many bricks will be used to build a wall is 40 feet high?

To solve e the above question, we have:

20 feet high = 250 bricks

40 feet high = x bricks

Cross Multiply

20 feet × x bricks = 40 feet × 250 bricks

x bricks = 40 feet × 250 bricks/20 feet

x bricks = 500 bricks

Therefore, 500 bricks will be used to build a wall is 40 feet high.
