Answer:

39 × 75

Step-by-step explanation:

Since, the shape of the twin mattress is rectangular,

Given,

The length of the mattress = 75 inches,

Width of the mattress = 39 inches,

Now, the the area of the top of the mattress( which is covered by the quilt) = Area of the mattress

We know that,

The Area of a rectangle =  Length × Width

Hence, the area of the top of the mattress = 75 × 39

= 39 × 75

Third option is correct.
