Question

Which one of the following expressions gives the algebraic expression for the given visual model?

• A. 4q + 16
• B. 4q + 4
• C. q + 8
• D. 4q + 8

Answer 1

The correct option is A 4q + 16

There are 4 rows.

In a row, 1 blue tile and 4 yellow tiles are there.

Dimensions of the visual model is (q + 4) units and 4 units.

Area of the model is

4(q + 4)

= 4(q) + 4(4)

= 4q + 16

Hence, the algebraic expression that represents the model is 4q + 16.
