Question

Without drawing, tell how many different rectangles have an area of 5 square units. Explain.

Answer 1

Only 1 rectangle has an area if 5u² or 5 square units. This is because 5 is a prime number meaning only 2 numbers can be the factors which are 1 and in this case 5. So the width of 1 times the length of 5 will give you the total area of 5.
