Answer:

(C) and (A)

Step-by-step explanation:

(A) It is given that ABCD is a parallelogram with base DC=4 units and height is 6 units, thus the area of parallelogram is given as:

\(A=Base{\times}height\)

Substituting the given values, we have

\(A=4{\times}6\)

\(A=24 sq units\)

Therefore, the area of the parallelogram is 24 square units.

Hence, Option (C) is correct.

(B) We are given a triangle which is inside the rectangle with sides 2 units × 3 units, therefore the area of the triangle ABC will be:

\(Area=\frac{1}{2}(area of rectangle)\)

Thus, the area of triangle ABC will be one-half the area of a rectangle with sides 2 units × 3 units.

Hence, option A is correct.

Answer:

1) 24 square units 2) It is one-half the area of a rectangle with sides 2 units × 3 units.

Step-by-step explanation:

\(Area_{Parallelogram}=width*length\\A=6*4\\A=24 u^{2}\)

The area of a parallelogram is calculated by width times height, height is always a perpendicular segment.

2)Which statement best describes the area of Triangle ABC shown below?

Counting the squares, we can see there is a 2 squares for the base and 3 for the height.

\(\bigtriangleup ABC=\frac{b*h}{2}\\ \bigtriangleup ABC=\frac{2*3}{2}=3\)

The Area of a Rectangle is 6, for S Rect. =2*3=6 One rectangle comprises two triangles.
