Problem 12 Part A (10 points) Write a function named stair()that takes two parameters:

Input: t -- a turtle treadSize

stair() should draw a rectangle, the long sides of which are of

length treadSize and the short sides are of length treadSize/4 (see illustration below).

Part B (10 points) Write a function named stairs() that takes three parameters:

Input: size, num, offset,

should call stair() repeatedly to draw num stairs, each with long sides of length size, and with

each stair offset to the right and above the preceding one by distance offset.

For example, the function call stairs(50, 5, 25) should produce the following output.
