Atriangle has an area of 30 cm². the base and height are scaled by a factor of 3. what is the area of the resulting triangle? enter your answer in the box.

The area of the resulting triangle is

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

let

z------> the scale factor

x------> the area of the resulting triangle

y-----> the area of the original triangle

so

we have

substitute and solve for x

your answer is the frist one

hop i

a 90 degree rotation across the the origin followed by a reflection across the x-axis.
