The triangles are similar. The area of the larger triangle 603cm2. what is the area of the smaller triangle?
tekilochka [14]

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
