Answer:
6 cm
Step-by-step explanation:
Let k represent the scale factor between ΔABC and ΔDCA. Then ...
... CA = k·BC
... AD = k·CA
So, AD/BC = k·(k·BC)/BC = k² = 9/4
Then k = √(9/4) = 3/2, and ...
... CA = (3/2)·BC = (3/2)·(4 cm)
... CA = 6 cm
Answer: 10 feet
The ratios:
1 inch : 2 feet
5 inch : <em>x</em> feet
Finding x:
1 * 5 = 5
2 * 5 = 10
The real robot would be <u>10</u> feet tall.
