Answer:

Area of the new triangle = 0.28125ab square units.

Step-by-step explanation:

Take an example of a right-angled triangle with sides a, b and c.

Where a is the height and b is the base and c is the hypotenuse.

Area of the original triangle is given by: \frac{1}{2} × base × height

In our case, area =  \frac{1}{2} × a × b

After the dimensions of our triangle have been decreased to 75%, new area becomes:

\frac{1}{2} × 0.75a × 0.75b = 0.28125ab square units.

c) Biyectiva: es cuando la correspondencia es inyectiva y sobre inyectiva a la vez

Correspondencia unívoca : es una correspondencia donde cada elemento del conjunto origen se corresponde con solo un elemento del conjunto de llegada.

Correspondencia biunívoca  es cuando a cada elemento del conjunto origen se corresponde con solo un elemento del conjunto llegada, y viceversa
