Answer:

The complete area of the given figure is [tex](2 b^3) cm^2[/tex]

Step-by-step explanation:

Total number of rows = 2

Squares in each row = b

So, the total number of  squares in 2 rows = 2 x ( Squares in 1 row ) = 2 x  b

Also, side length of 1 square = b cm

As we know, AREA OF SQUARE  = SIDE x SIDE

So here, area of 1 square  = Side x side  = b cm  x b cm = [tex](b^2) cm^2[/tex]

⇒ The area of total (2b) squares  = 2 b x ( Area of  1 square)

[tex]= 2 b \times (b^2) = 2 b^3[/tex]

Hence, the complete area of the given figure is [tex](2 b^3) cm^2[/tex]

The  simplified expression for area of two rows of b squares with side lengths of b centimeters is [tex]\rm \bold{2b^3 cm^2}[/tex]

We have to find and simplify an expression for the area of two rows of b squares with side lengths of b centimeters.

Given that

There are b squares in 1 row

So the total number of squares in 2 rows = 2b

[tex]\rm The \; dimensions\; of \;one\; square = b \; (cm ) \times b\; (cm)[/tex]

[tex]\rm The\; area\; of \; square \; with \; side \; s \; cm \; is \; given\; by \; s^2 cm^2[/tex]

[tex]\rm So \; the \; area\; of \; single\; square\; in\; the\; given \; figure = b \times b = b^2 cm^2 \\[/tex]

[tex]\rm So \; the \; total\; area\; of \; all \; the \; squares\; in \; the \; given\; figure = 2b \times b^2 cm^2 = \bold{2b^3 cm^2}[/tex]

So  the simplified expression for area of two rows of b squares with side lengths of b centimeters is [tex]\rm \bold{2b^3 cm^2}[/tex]
