Answer:
Step-by-step explanation:
In order to find the area of a square you take the base and multiply it by the height.
Base x Height = Area
In this case you have 7cm as the base and 6cm as the height.
All you have to do after that is multiply the two together.
Make sure that you remember to put the unit (cm) and make sure that it is 
because some teachers are uptight about that stuff.

(2x - 3) (3x + 4) = 6x² + 8x - 9x - 12 = <u>6x² - x - 12 </u>
The work done by the gas when the gas expands will be 567.65 ft-lb.
<h3>What is the work done for an isothermal process?</h3>
The Pressure is inversely proportional to the volume.
Let the initial pressure and initial volume be P₁ and V₁, and the final volume be V₂.
Then the work done by the gas will be
WD = P₁ V₁ ln (V₂ / V₁)
A quantity of the gas with an initial volume of 2 cubic feet and an initial pressure of 700 pounds per square foot.
The gas expands to a volume of 3 cubic feet.
Then the work done by the gas will be
WD = 700 x 2 x ln (3/2)
WD = 1400 x 0.405
WD = 567.65 ft-lb
The work done by the gas when the gas expands will be 567.65 ft-lb.
