please tell the answer of 3rd one please

Answer 1

Answer:

16 cm squared

Step-by-step explanation:

SInce the opposite sides have equal values, it forms a rectangle.

Opposite sides of a rectangle are always parallel.

Triangles on the same base between 2 parallels will have equal areas.

The value of the bases the triangles are on are the same, since the quadrilateral is a rectangle.

Area of Triangle 1 = 1/2 * h * b

h = 2cm

b = 8cm

1/2 * 2 * 8 = 8 cm squared.

To find area of the quadrilateral, we need to add the area of triangle 1 and triangle 2. But since they are equal in areas, 2 * 8 = 16 cm squared, which is the answer.

Therefore, area of the quadrilateral is 16 cm squared.
