Answer:

435 ft

Step-by-step explanation:

area of triangle:

A = (b x h) : 2

A = (15 x 4) : 2

A = 60 : 2

A = 30 ft

area of rectangle:

A = b x h

A = 25 x 15

A = 375 ft

area of the yard = area of the triangle + area of the triangle + area of the rectangle (Here, both triangles have the same area.)

area of the yard: 30 + 30 + 375 = 435 ft.

So, the area of the yard is 435 ft.

I hope this was helpful. :)

zzz [600]

Answer:

f(x)=nx

or

f(x)=9.50x

Step-by-step explanation:

Let x be the amount of hours and n be the hourly rate (9.50).

f(x)=nx

or if you prefer to use 9.50 instead of n, the function would be:

f(x)=9.50x
