The given product is:


3(4b+12c+11)

It is required to use a rectangular array to write the product in standard form.

Draw the rectangular array as shown:

Partition the sum to give small rectangles as shown:

Calculate the area of each rectangle by multiplying the width and length, then find the sum to write the product in standard form:

Write the areas as a sum:


12b+36c+33

Hence, the required product in standard form is 12b+36c+33.

The required product in standard form is 12b+36c+33.
