Reasons:
The process of multiplication of factors using a model includes;
- Creating a table that have the number of rows and columns equal to the values in the denominator of the two fractions respectively
- Shading the number of columns given by the numerator of the fraction that has a denominator equal to the number of columns in the table
- Shading the number of rows given by the numerator of the fraction that has a denominator equal to the number of rows in the table
- Ensuring that the common area are shaded to a different color

Use pythagora's theorem to solve it
c^2=a^2+b^2
x^2=(3/4)^2+1^2
x^2=25/16
x= 5/4 = 1 1/4 inch
therefore it is B
