Answer:

a(h) = 1.25h²

Step-by-step explanation:

The formula for the area of a rectangle is ...

A = HW . . . . . where H represents the height and W represents the width

If the image has a height of h, then the width is 1.25 times that, or 1.25h. Putting these values into the formula, we have ...

A = h·(1.25h)

A = 1.25h²

In function form, we can write a(h), area as a function of height, as ...

a(h) = 1.25h²
