Answer:
28 bricks.
Step-by-step explanation:
The length of the garden = [tex]6\frac{2}{3}[/tex] feet
= [tex]\frac{20}{3}[/tex] feet
The width of the garden = [tex]2\frac{2}{3}[/tex] feet
= [tex]\frac{8}{3}[/tex] feet
Now we will calculate the perimeter of the garden
Perimeter = 2(Length + width)
= 2 ( [tex]\frac{20}{3}[/tex] + [tex]\frac{8}{3}[/tex] )
= 2 ( [tex]\frac{20+8}{3}[/tex] )
= 2 × [tex]\frac{28}{3}[/tex]
= [tex]\frac{56}{3}[/tex] feet
Each brick is [tex]\frac{2}{3}[/tex] foot long. So we divide perimeter of the garden by the length of each brick.
= [tex]\frac{56}{3}[/tex] ÷ [tex]\frac{2}{3}[/tex]
= [tex]\frac{56}{3}[/tex] × [tex]\frac{3}{2}[/tex]
= [tex]\frac{56}{2}[/tex]
= 28 bricks
Juan needs 28 bricks.
