Answer 1

Answer: n=4

Explanation:

Given

dimension of the entire ground is
`28* 90\ yards^2`

dimension of the porch is

`l=90-2* 14=62\ yards\\w=10\ yards`

`\therefore 62* 10\ yard^2`

Area of the entire field is

`\Rightarrow A_1=90* 28=2520\ yard^2`

Area of Porch

`\Rightarrow A_2=62* 10=620\ yard^2`

Now , the area of lawn is

`\Rightarrow A_l=A_1-A_2\\\Rightarrow A_l=2520-620=1900\ yard^2`

No of bags(n) required is

`\Rightarrow n=(1900)/(600)=3.167\\\text{i.e. n=4}`
