Answer:
324 ft²
Step-by-step explanation:
Given 2 similar figures with ratio of sides a : b , then
ratio of areas = a² : b²
Here ratio of sides = 3 : 18 = 1 : 6
ratio of areas = 1² : 6² = 1 : 36
That is the area of the larger parallelogram is 36 times the smaller
area of larger parallelogram = 36 × 9 = 324 ft²
