Asection of a rectangle is shaded. the area of the shaded section is 63 square units. what is the value of x?

Step-by-step explanation:

We have been given a graph of a rectangle. The area of the shaded section is 63 square units. We are asked to find the value of x.

We can see from our given graph that shaded section forms a trapezoid, so we will use area of trapezoid formula to find the value of x.

, where, a and b represents the parallel sides of trapezoid and h represents height of trapezoid.

Upon substituting our given values in above formula we will get,

Upon dividing both sides of our equation by 3.5 we will get,

Let us subtract 7 from both sides of our equation.

Therefore, the value of x is 11 units.
