Step-by-step explanation:

Your question do not have enough details for it to be answered. I will solve your question on a general terms using the attached image of a trapezoid

Given

From the attachment, we have:

--- height

The perimeter (P) of a trapezoid is:

Substitute values for AD, BC

Next, is to calculate the lengths of AB and CD or the sum: AB + CD

The area of a trapezoid is:

Substitute values for Area and h

Multiply both sides by 2

Divide both sides by 60

Substitute 286 for AB + CD in:

The perimeter of the backyard is 466ft.

The above steps should give you a hint on how to solve your actual question.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
