Answer:

The correct answer is C

Step-by-step explanation:

The first composition performed by student is rotation of 90° clockwise on A to get A'' then A' can't be obtained either by reflecting A'' across x-axis or y-axis.

But on rotating A by 90° counterclockwise to get A'' and reflecting this A'' across x-axis we get the required composition.

So, student need to rotate the figure 90° anticlockwise instead of 90° clockwise

So, The right answer is C.

Ainat [17]

Answer:

Option A, Option C, Option E

Step-by-step explanation:

The area of a kite can be identified through 1 / 2 of the multiplication of each diagonal. The first diagonal is equivalent to the addition of 50 cm and 10 cm, while the second is of length 20 cm + 20 cm.

$1 / 2 * ( 50 + 10 ) * ( 20 + 20 ),\\1 / 2 * ( 60 ) * ( 40 ),\\( 30 ) * ( 40 ),\\\\Area of Kite = 1200 square cm$

Consider the first option. If we take a look at the bit 2 * ( 1 / 2 * 20 * 50 ) the 2 and 1 /2 cancel each other out, leaving you with 20 * 50 = 1000 . Respectively in the expression 2 * ( 1 / 2 * 20 * 10 ) the 2 and 1 / 2 cancel each other out, leaving you with 20 * 10 = 200;

$1000 + 200 = 1200 square cm,\\Option A - Correct!$
