Given that,
The height of a trapezoid is (2x + 9).
The bases can be expressed as (3x - 7) and (x + 5).
To find,
An expression represent the area of the trapezoid.
Solution,
The formula for the area of trapezoid is given by :
Put all the values,
So, the area of the trapezoid will be
There are 12 project managers that are employed by Mr. Wells
<h3>Further explanation</h3>Solving linear equation mean calculating the unknown variable from the equation.
Let the linear equation : y = mx + c
If we draw the above equation on Cartesian Coordinates , it will be a straight line with :
<em>m → gradient of the line</em>
<em>( 0 , c ) → y - intercept</em>
Gradient of the line could also be calculated from two arbitrary points on line ( x₁ , y₁ ) and ( x₂ , y₂ ) with the formula :
If point ( x₁ , y₁ ) is on the line with gradient m , the equation of the line will be :
<em>Let us tackle the problem!</em>
This problem is about Directly Proportional.

<em>There were 5 project managers for every 50 engineers.</em>
