Math worksheet using area models and the distributive property to calculate the total area of rectangles by splitting them into smaller parts.
A math worksheet with four sections (a, b, c, d) showing grid-based rectangles divided into shaded and unshaded parts. Each section includes a multiplication problem using the distributive property to find the total area by adding the areas of smaller rectangles. The grids are labeled with side lengths and equations are partially filled in for students to complete.
