Arectangle is removed from a right triangle to create the shaded region shown below. find the area of the shaded region. be sure to include the correct unit in your answer.

29.5 yd²

Step-by-step explanation:

First we find the area of the triangle.

The base of the triangle is 5+4 = 9 yd.

The height of the triangle is 6+5 = 11 yd.

The formula for the area of a triangle is A = 1/2bh; this gives us

A = 1/2(9)(11) = 1/2(99) = 49.5 yd²

Next we find the area of the rectangle that is removed.  The length of the rectangle is 4 and the width is 5.  The area of a rectangle is given by

A = l*w; for our rectangle, we have

A = 4(5) = 20 yd²

The shaded region will have an area of

49.5 yd² - 20 yd² = 29.5 yd²

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
