Worksheet: Distributive Property of Multiplication

Download

In this worksheet, we will practice using the distributive property of multiplication to multiply numbers up to 10×10 by breaking the numbers apart.

Q1:

The diagram shows a rectangle of sides π‘Ž and 𝑏+𝑐. Its area is thus π‘ŽΓ—(𝑏+𝑐), also written as π‘Ž(𝑏+𝑐). Work out the area of the two rectangles that make up the bigger rectangle to find an equivalent expression to π‘Ž(𝑏+𝑐).
