Answer:

f(15)=525\ ft^{2}

f(15) is the area of the rectangular garden for a width of 15 ft

Step-by-step explanation:

we know that

f(x)=x(2x+5)

where

x----> is the width of the rectangular garden

(2x+5) ----> is the length of the rectangular garden

so

f(15) -----> is the value of f(x) for x=15 ft

That means

f(15) is the area of the rectangular garden for a width of 15 ft

substitute the value of x and solve

f(15)=15(2(15)+5)

f(15)=525\ ft^{2}
