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

Ronch [10]

Answer:

The complete area of the given figure is $(2 b^3) cm^2$

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 = $(b^2) cm^2$

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

$= 2 b \times (b^2) = 2 b^3$

Hence, the complete area of the given figure is $(2 b^3) cm^2$

The table shows the distance the students a group of students walked during after-school practice. What was the total distance,

ser-zykov [4K]

First let's convert the decimal numbers to mixed numbers:

$\begin{gathered} 3.4=3+0.4=3+\frac{4}{10}=3+\frac{2}{5}=3\frac{2}{5} \\ 1.75=1+0.75=1+\frac{75}{100}=1+\frac{3}{4}=1\frac{3}{4} \\ 2.25=2+0.25=2+\frac{25}{100}=2+\frac{1}{4}=2\frac{1}{4} \end{gathered}$

Now, adding all the numbers, we have:

$\begin{gathered} (3+\frac{2}{5})+(3+\frac{1}{5})+(1+\frac{3}{4})+(2+\frac{1}{4})+(1+\frac{7}{10}) \\ =(3+3+1+2+1)+(\frac{2}{5}+\frac{1}{5}+\frac{3}{4}+\frac{1}{4}+\frac{7}{10}) \\ =10+(\frac{3}{5}+1+\frac{7}{10}) \\ =11+(\frac{6}{10}+\frac{7}{10}) \\ =11+\frac{13}{10} \\ =12+\frac{3}{10}=12\frac{3}{10} \end{gathered}$

So the correct option is B.
