Find The Area Of The Composite Shape Below The Area Of Quadrilateral ABCD Is Square Units class=

Sagot :

Answer:

25 square units

Step-by-step explanation:

Draw a segment from point B to point (3, 0). Call point (3, 0) point E.

Now you have a trapezoid, ABED, with parallel sides AD and BE, and a triangle, BEC. We find the area of the trapezoid and the area of the triangle and add then together.

total area = area of trapezoid + area of triangle

total area = (B + b)h/2 + bh/2

total area = (4 + 3)(6)/2 + 2(4)/2

total area = 21 + 4

total area = 25

Answer: 25 square units
