Answer 2

6 pounds of fertilizers are needed for garden area of 180 square foot.

Explanation:

Let 'x' pounds of fertilizers be needed for 180 square foot garden.

Given:

4 pounds of fertilizer needed for an area of 120 square foot.

The area of the garden given is 180 square foot.

Now, as per question:

4 pounds of fertilizer is equivalent to an area of 120 square foot.

Therefore, 'x' pounds of fertilizer is equivalent to an area of 180 square foot.

Applying proportion and cross multiplying method, we get:

`(x)/(180)=(4)/(120)`

`120x=4* 180\\\\120x=720\\\\x=(720)/(120)\\\\x=6\ pounds`

Therefore, 6 pounds of fertilizers are needed for garden area of 180 square foot.
