Answer 1

Answer:

1728.

Step-by-step explanation:

It is given that The numbers of different plant types are in the ratio  

Tall green:Tall yellow:Short green:Short yellow = 8:5:2:1.

Let the numbers of Tall green, Tall yellow, Short green:, Short yellow are 8x, 5x, 2x, x respectively.

Number of green plants $=8x+2x=10x$

It is given that there are 1080 green plants.

$10x=1080$

$x=108$

Number of total plants $=8x+5x+2x+x=16x$

$16x=16(108)=1728$

Therefore, total plants are in Gregor's yard is 1728.
