Question

The length of a rectangle with area 38 in2 depends on its width. Write the formula that describes the length of the rectangle as a function of its width.

Answer 1

L = 38/W

Explanation:

The area of a rectangle is computed by multiplying length by width. For length L and width W in inches, your rectangle has area ...

A = LW

38 = LW

Then the length can be found by dividing the equation by W:

L = 38/W
