Check the picture below.

$\bf V=3354~in^3\qquad \qquad 3354=6(w-12)(w+18)
\\\\\\
\cfrac{3354}{6}=w^2+6w-216\implies 559=w^2+6w-216
\\\\\\
0=w^2+6w-775\implies 0=(w+31)(w-25)\implies w=
\begin{cases}
-31\\
\boxed{25}
\end{cases}$

since the width is just a dimension unit, it can't be -31.

what is the length? well, the length is w + 30.

A rectangular board is 1.6 meters long and 1.2 meters wide. What is the area of the board in square millimeters? Do not round yo

Arisa [49]

<h2>Area of rectangular board is 1920000 square millimeters</h2>

Step-by-step explanation:

A rectangular board is 1.6 meters long and 1.2 meters wide.

Here we need to find the area of the board in square millimeters.

Length = 1.6 m= 1.6 x 1000 = 1600 mm

Width = 1.2 m= 1.2 x 1000 = 1200 mm

Area = Length x Width

Area = 1600 x 1200

Area = 1920000 square millimeters

Area of rectangular board is 1920000 square millimeters
