This is not a Geography question. You might want to try it under the categories Homework Help or Mathematics.

In both cases you are starting with an object (called the preimage), and enlarging it to get the final result.

a=(1/2)b*h. The base is increasing by a factor of 3 AND the height is increasing by a factor of 3. So the area increased by a factor of 9. Divide the new area by 9 and the original/preimage area =1 cm^2

"In general for an area, a, with some scale factor greater than 1, f,
new area=a*f^2 or rearranged a=new area/f^2
"

The particular rectangle will be enflamed by the component of 3/3. The location increased with a issue connected with (a few/a couple of)enqa_only two or hunting for/5. Flourish the newest place aside some/nine and also the authentic spot will be 24cmenqa_only two.
