Answer:
315 cm²
Step-by-step explanation:
Given the scale factor of 2 similar figures is a : b , then
ratio of areas = a² : b²
Here the scale factor = 7 : 21 = 1 : 3 , thus
ratio of areas = 1² : 3² = 1 : 9
That is the area of the enlargement is 9 times the original, so
area of enlargement = 35 × 9 = 315 cm²
Answer:A= -1
B=-9
C=9
D=3
E=3
F=2
G=1.5

-2 +2= 2 +2= 4 +2= 6 ...
You simply divide, since it's a fraction. If you divide 14 b7 25, you get an answer of 0.56. :)
9 rows time 36 trees equals 324 trees
