Find the area of the shaded region. Round to the nearest hundredth where necessary. Remember: you are subtracting the areas.

Given:

The base of the given figure = 23.8 ft

Height of the parallelogram = 15 ft

To find the area of the shaded region.

Formula

where, be the area of the shaded region

be the area of the parallelogram.

be the area of the triangular part.

Now,

Putting, Base = 21, Hypotenuse = 23.8 we get,

or,

or,

Therefore,

Area of the parallelogram sq ft = 357 sq ft

Area of the triangle = sq ft = 117.6 sq ft

So,

The area of the shaded part = (357-117.6) sq ft = 239.4 sq ft

Hence,

The area of the shaded part is 239.4 sq ft.

step-by-step explanation:

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
