The length of a rectangular garden abcd is 9 feet more than its width. it is surrounded by a brick walkway 4 feet wide as shown below. suppose the total area of the walkway is 400 square feet. what are the dimensions of the garden? i keep trying to do it but it doesn't work.

The dimensions of the garden are

Length  and Width

Step-by-step explanation:

Let

x----> the length of the rectangular garden

y ---> the width of the rectangular garden

Aw ----> the area of the walkway

we know that

----> equation A

so

----> equation B

Substitute equation A in equation B

Find the value of x

therefore

The dimensions of the garden are

Length

Width

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.
