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

2b³ cm²

Step-by-step 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

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
