Question

Find and simplify an expression for the area of two rows of b squares with side lengths of b centimeters .

Answer 1

2b³ cm²

Explanation:

The Area of each square :

Area of a square = a² ; where a = side length

The side length = b

Hence, Area, A = b² = b² cm²

The total number of squares:

Number of rows * number of squares per row

2 * b = 2b

Therefore, total area :

Total number of squares * area of each square

(2b) * b²

= 2b³ cm²
