Question

A garden is 6 2/3 feet long and 2 2/3 feet wide. Juan is putting a brick border around the garden. Each brick is 2/3 foot long. How many bricks does Juan need?

Answer 1

Juan need 14 bricks for making garden's border.

Answer 2

28 bricks.

Explanation:

The length of the garden =
`6(2)/(3)` feet

=
`(20)/(3)` feet

The width of the garden =
`2(2)/(3)` feet

=
`(8)/(3)` feet

Now we will calculate the perimeter of the garden

Perimeter = 2(Length + width)

= 2 (
`(20)/(3)` +
`(8)/(3)` )

= 2 (
`(20+8)/(3)` )

= 2 ×
`(28)/(3)`

=
`(56)/(3)` feet

Each brick is
`(2)/(3)` foot long. So we divide perimeter of the garden by the length of each brick.

=
`(56)/(3)` ÷
`(2)/(3)`

=
`(56)/(3)` ×
`(3)/(2)`

=
`(56)/(2)`

= 28 bricks

Juan needs 28 bricks.
