Answer:
190 square foot
Step-by-step explanation:
School yard = 950 square foot
20% of school yard for student to start garden
Therefore
20/100 x 950
= 190 square foot
The part of 950-sq.-foot space the students can use is: 190-sq.-foot.
Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
Students can use 20% of 950-sq.foot.
Now, 20% of 950-sq.-foot is derived as:
[tex]\dfrac{950}{100} \times 20 = 190[/tex]
Thus, the part of 950-sq.-foot space the students can use is: 190-sq.-foot.
