ANSWER
(a) h = 28/w
Step-by-step explanation
We have that the Area of the rectange is given as 28 square inches.
We know that the area of a rectangle is found by using:
A = w * h
where w = width, h = height.
Therefore, we have that:
28 = w * h
(a) To express the height in terms of width, we simply make h the subject of the formula above:
(b) The perimeter of a rectangle is given as:
P = 2(w + h)
Now, put h as 28/w:
