Answer:
The answer is one yard (wide) and 1.33 yard (high.)
Step-by-step explanation:
A foot is equivalent to the third part of a yard, meaning that three feet are necessary to complete one. According to the question, it is necessary to add half foot to the length and the width for seams. For the width we need two and a half feet plus half feet, completing one yard; for the length it is necessary to use three and a half feet plus half feet, making 4 feet or one yard and a third.
