The smaller triangle is scaled by a factor of (18 cm)/(54 cm) = 1/3 of the larger triangle. The ratio of areas is the square of that scale factor.
small triangle area = (1/3)^2 × large triangle area
... = (1/9) × 603 cm^2
... = 67 cm^2
The appropriate choice is
... C. 67 cm^2
The answer is 24 but if you want check us a calculator
It's different because they're comparing two different ways
Example:
2 red apples, 5 apples in total- The ratio would be 2:5
5 green apples, 2 red apples- The ratio would be 5:2
I don't understand my own example but whatever.
